Description
技术领域
本发明涉及一种用于制备稀土钒酸钇的方法，尤其涉及的是一种稀土钒酸钇、制备方法及应用。
背景技术
近年来，稀土钒酸盐(LnVO4)由于具有电子结构独特、原子磁矩大和自旋轨道效应强等效应，使其显现出磁性、光催化活性、化学和热稳定性、导电性、气敏性等良好的材料性能，因而在催化、发光材料、激光基质材料、磷光材料、介电材料、磁阻材料等领域得到了广泛的应用，尤其稀土钒酸盐发光材料在国内外的发展速度惊人，形成了相当大的生产规模和广阔的市场，其产值和经济效益都很高，从而为许多专家学者所关注。
目前，关于钒酸钇的制备方法有超声法、溶胶凝胶法、固相法等等。超声法反应不易控制、有副反应发生，微波反应器价格昂贵，只能限制在小规模合成上；溶胶凝胶法过程所需时间较长，溶胶中存在大量微孔，在干燥过程中又将会逸出许多气体及有机物，并产生收缩；固相法制得产品不易均匀，微粒易团聚，微粒直径分布宽。因此，急需研发一种操作简单、耗时短、绿色环保的钒酸钇制备方法。
发明内容
本发明的目的在于克服现有技术的不足，提供了一种稀土钒酸钇、制备方法及应用，实现快速的稀土钒酸钇的合成。
本发明是通过以下技术方案实现的，本发明包括以下步骤：
(1)配置悬浮液
使用去离子水和三亚乙基四胺溶液配置硝酸钇和正钒酸钠的悬浮液，所述悬浮液中，Y3+离子和VO4 3-离子的摩尔浓度比为1.0～1.2：1，三亚乙基四胺TETA和H2O的体积比为1:1～17；
(2)水热反应制备米粒状钒酸钇
将上述悬浮液转移至密闭容器中，密封后在50～200℃反应8～24h，收集固体得到米粒状钒酸钇。
所述步骤(1)中，所述悬浮液的配置包括以下步骤：
(11)首先将硝酸钇溶解于去离子水中，再加入三亚乙基四胺溶液配置得到硝酸钇溶液；
(12)然后将正钒酸钠溶解在去离子水中得到正钒酸钠溶液；
(13)在室温下将步骤(11)的硝酸钇溶液和步骤(12)的正钒酸钠溶液迅速混合搅拌即可。
作为本发明的优选方式之一，所述步骤(1)中，三亚乙基四胺TETA和H2O的体积比分别为1:1，1:3，1:8，1：17。
作为本发明的优选方式之一，所述步骤(2)中的密闭容器为带聚四氟乙烯内衬的不锈钢反应釜。
作为本发明的优选方式之一，所述悬浮液在密封容器中密封后，放置于烘箱中180℃反应12h。
一种如所述制备方法制得的稀土钒酸钇。
所述稀土钒酸钇为结构均匀一致的米粒结构。
一种稀土钒酸钇在制备发光材料中的应用。将本发明的稀土钒酸钇作为基质应用在发光材料中，通过掺杂，获得具有优良的发光效率和化学稳定性。
稀土钒酸盐材料有很丰富的光学特性，如光致发光，电致发光，荧光特性，吸光特性等。而YVO4:Ln(Ln＝Eu，Tm，Dy)是一种性能优良的红色荧光材料，其中稀土离子的4f电子跃迁所对应的发射为锐线光谱，受外场的影响小，并且具有优良的发光效率和化学稳定性，可广泛应用于高质量的彩色电视机荧光粉，灯用荧光粉，医用荧光粉，光学玻璃，激光材料等。由此可见，以纳米级稀土钒酸盐为基质的发光材料是一种很有应用前途的发光材料。
本发明相比现有技术具有以下优点：本发明制得的产物纯度高，使用原料组分少，配比条件更易调控，制备工艺简单，成本低廉，能够制得均匀一致的米粒状钒酸钇。
