100μm。
The detection method of stability of photoluminescence is:The method of testing of stability of photoluminescence is mainly included in high temperature blue light illumination (70
DEG C, 0.5W/cm2), under the aging condition such as hot and humid (65 DEG C/95%RH) and high-temperature storage (85 DEG C), detect quantum dot film
Efficiency change.
The detection method of quantum dot light emitting efficiency is:By the use of 450nm blue LED lamps as light source, distinguished using integrating sphere
Test Blue backlight spectrum and the spectrum through quantum dot film, using the integral area of spectrogram quantum dot luminous efficiency is calculated.
Specific test result is shown in Table 1.
Table 1
Note:Above efficiency is quantum dot light emitting efficiency, and for relative efficiency, the efficiency of comparative example 1 is set to into 100%,
Other efficiency are to make ratio with the efficiency of comparative example 1 to draw.
Quantum dot light emitting efficiency=(red quantum point absorbs peak area+green quantum dot and absorbs peak area)/(Blue backlight
Peak area-pass through the unabsorbed blue peak area of quantum dot film) × 100%.
Knowable to the data of table 1, comparative example 1 adopts the preferable inorganic barrier film of barrier property of the prior art, this Shen
The barrier property of each quantum dot film in embodiment 1 please to embodiment 9 is suitable, but, the quantum dot film of these embodiments
Cost it is more much lower than comparative example 1;Embodiment 10 is poor due to the block-water performance of the material of water blocking layer, embodiment 11 due to
The oxygen resistance of the material of oxidation prevention layer is poor so that although quantum dot film barrier property is than the difference of comparative example 1, its cost
It is more much lower than comparative example 1;Embodiment 2 is due to increased bonding enhancement layer and frosted layer so that the efficiency before and after aging compares
Embodiment 1 it is big, embodiment 4 is processed due to the surface to the 3rd substrate layer so that the quantum dot film for ultimately forming
Efficiency after aging is big than embodiment 2, and embodiment 9 is due to increased a water blocking layer and an oxidation prevention layer, its initial effect
Rate is less than embodiment 1, but the attenuation degree of its efficiency is less.
As can be seen from the above description, the application the above embodiments realize following technique effect:
1) the organic Obstruct membrane in the application not only has preferable water and oxygen barrier property, and organic Obstruct membrane is significantly
The preparation technology of Obstruct membrane is simplified, production cost is reduced.
2) the quantum dot film in the application on the surface of quantum dot due to being provided with above-mentioned organic Obstruct membrane so that amount
Son point film not only has preferable water and oxygen barrier property, also with relatively low Obstruct membrane cost.
3) because with above-mentioned quantum dot film, its manufacture craft is relatively easy, produces in the backlight module of the application
This is relatively low, and lasts a long time.
4) because with above-mentioned quantum dot film, its manufacture craft is relatively easy in the light-emitting device in the application, production
Cost is relatively low, and lasts a long time.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent, improvement etc., should be included within the protection domain of the application.
