Abstract
Description
本発明は光下で発光または発色する装飾材料に関するものである。尚、本発明において、「装飾材料」とは単結晶材料およびその単結晶材料を加工し「ブロック」形状にしたもの、及び微結晶又は粉末状にしたもの、これらのブロック体、微結晶、粉末を単体で使用したもの、他の原材料に分散したもの、本体の一部に配したもの、繊維状のものに付着させて用いるものなどを呼ぶ。 The present invention relates to a decorative material that emits light or develops color under light. In the present invention, the term “decorative material” refers to a single crystal material, a single crystal material processed into a “block” shape, and a microcrystal or powder, and these block bodies, microcrystals, and powders. Is used alone, is dispersed in other raw materials, is disposed on a part of the main body, or is attached to a fibrous material.
一般に、可視光線の波長範囲は３６０〜４００ｎｍから７６０〜８３０ｎｍであり、紫外線の波長範囲は３６０〜４００ｎｍ（可視光線の短波長端として）から約１ｎｍであり、赤外線の波長範囲は７６０ｎｍ〜８３０ｎｍ（可視光線の長波長端として）から約１ｍｍである。赤外線源としては、太陽が知られている。太陽スペクトルは可視光線のスペクトルを中心にして赤外線、紫外線、電波、及びＸ線を含む。なお、蛍光灯は、白色に近い光を得るための光源として用いられる。 In general, the wavelength range of visible light is 360 to 400 nm to 760 to 830 nm, the wavelength range of ultraviolet light is 360 to 400 nm (as the short wavelength end of visible light), and about 1 nm, and the wavelength range of infrared light is 760 to 830 nm ( About 1 mm from the long wavelength end of visible light. The sun is known as an infrared source. The solar spectrum includes infrared rays, ultraviolet rays, radio waves, and X-rays centered on the visible light spectrum. The fluorescent lamp is used as a light source for obtaining light close to white.
貴金属類や宝石類は、ネックレス、ピアスなどに代表されるアクセサリーや、種々のオブジェやインテリアなどの装飾材料として多用されている。しかしながら、これらの材料は暗中で発光することはなく、紫外線（例えば、ブラックライト）や赤外線のような、代表的な可視光線とは波長が異なる電磁波を多く放射する光源の下で、一般的可視光線下とは異なり、発光したり発色したりすることはない。公知のように、ブラックライトは近紫外線又は特定の波長をもつ紫外線を多く含む光源である。 Precious metals and jewelry are widely used as accessories such as necklaces and earrings, and as decorative materials for various objects and interiors. However, these materials do not emit light in the dark and are generally visible under a light source that emits many electromagnetic waves having wavelengths different from typical visible light, such as ultraviolet light (eg, black light) and infrared light. Unlike under light, it does not emit light or develop color. As is well known, a black light is a light source containing a lot of near ultraviolet rays or ultraviolet rays having a specific wavelength.
また、可視光線以外の紫外線又は赤外線下で発光又は発色を起こす材料を得るため、ダイヤモンドを始めとする、多くの装飾材料の結晶に、微量の他元素を添加することが検討されている。しかしながら、これについても実用に供することが可能な技術が、未だに得られていないのが現状である。なお、紫外線による励起で発光する材料が、例えば、特許文献１に開示されている。 In addition, in order to obtain a material that emits light or develops color under ultraviolet light or infrared light other than visible light, it has been studied to add a trace amount of other elements to crystals of many decorative materials such as diamond.

However, the material is obtained by firing a raw material powder having a predetermined composition, and the shape is a powder, and it is difficult to obtain it as a massive crystal.
また、前記特許文献１以外にも、蛍光体を得る技術が開示されているが、いずれも塊状の結晶で得られるものでなく、用途としては、プラズマディスプレイの蛍光体薄膜や、ガラス容器の装飾などに限定されているのが実情である。 Moreover, although the technique which obtains fluorescent substance other than the said patent document 1 is disclosed, all are not obtained with a block-like crystal, As a use, the fluorescent substance thin film of a plasma display, or the decoration of a glass container The fact is that it is limited to.

これらの布製品は可視光、紫外光、そして赤外光で異なる発色をすることを確認した。可視光、赤外光では無色透明であるが、紫外線を当てることで模様が浮き出る衣類、可視光で青色の布が赤外光で紫、紫外線でピンク〜赤色を示すもの、本材料を複数用いることで、当てる光の種類で全く異なる色柄を持つ衣類等を作成することができた。即ち、紫外線を当てることで、青、緑、ピンク、赤を基色とした色柄である。 These fabric products were confirmed to develop different colors with visible light, ultraviolet light, and infrared light. It is colorless and transparent with visible light and infrared light, but a pattern that appears when exposed to ultraviolet light, a blue cloth with visible light that shows purple in infrared light, pink to red with ultraviolet light, and multiple uses of this material As a result, we were able to create clothing with a completely different color pattern depending on the type of light applied. That is, it is a color pattern based on blue, green, pink, and red by applying ultraviolet rays.
なお、上記各実施例において、可視光線源としては、可視光線領域を多く含む蛍光灯を、紫外線源としては、可視光線の短波長端から紫外線領域を多く含むブラックライトを、赤外線源としては、可視光線領域の外に、赤外線を比較的多く含む太陽光を用いた。 In each of the above embodiments, as a visible light source, a fluorescent lamp including a large amount of visible light region, as an ultraviolet ray source, a black light including a large amount of ultraviolet region from a short wavelength end of visible light, as an infrared source, Sunlight containing a relatively large amount of infrared light was used outside the visible light region.
本材料は、使用範囲が従来よりも格段に広汎になり、ネックレス、ピアス、ブレスレット等をはじめとするアクセサリー類や、時計、キーボルダー、携帯機器等の日用品、雑貨や小物類、家具、大型の時計をはじめとするインテリアやオブジェの他に、化粧品、文房具、食器類、紙や布を含む繊維状のもの等に埋め込み、分散、付着させて用いられる等、様々な新規装飾用途に適している。 This material has a much wider range of use than before, accessories such as necklaces, earrings and bracelets, daily necessities such as watches, key boulders, portable devices, miscellaneous goods and accessories, furniture, In addition to interiors and objects such as watches, it is suitable for various new decoration applications such as cosmetics, stationery, tableware, fibrous materials including paper and cloth, etc. .
さらに、本材料は、紫外線や赤外線の有無や強度を検知するセンサー機能を有する製品にも広く利用できる。 Furthermore, the present material can be widely used for products having a sensor function for detecting the presence or intensity of ultraviolet rays or infrared rays.
また、本材料は、装飾効果を有する上述以外の日用品、洋服、かばん、小物を含む衣料品、壁紙、包み紙などの紙製品、ガラス板、樹脂板などの建材他に広く応用できることはいうまでもない。
In addition, this material can be widely applied to daily necessities other than the above that have a decorative effect, clothing including clothes, bags, small articles, paper products such as wallpaper and wrapping paper, building materials such as glass plates and resin plates, etc. Nor.
Claims (13)
The decorative material according to any one of claims 1 to 12, wherein the decorative material functions as an ultraviolet or infrared sensor.
