Description
技术领域
本发明属于上转换材料合成领域,更具体地,涉及一种上转换荧光粉及其制备方法和应用。
背景技术
利用980 nm半导体机关器来激发稀土掺杂上转换白光材料,潜在应用于白光激光器、平板显示、生物传感器、背光源和照明等,相比传统白光光源,稀土掺杂上转换白光具有无光漂白、色温易调、环保的优点,有效减少紫外污染,因此成为现在研究的热点。但是发光效率较低严重影响其应用化进程。目前公认上转换发光效率最高的基质是氟化钇钠(NaYF4),但由于在制备过程中会对环境造成一定的污染,同时热稳定性稍差。寻找一种发光强度大,热稳定性好的上转换材料尤为重要。
发明内容
本发明的目的在于提供一种上转换荧光粉。
本发明的另一目的在于提供上述荧光粉的制备方法和应用。
本发明的上述目的通过如下技术方案予以实现:
本发明提供了一种上转换荧光粉,化学组成通式为:Gd2-x-y-z Tm x Ho y Yb z (MoO4)3,其中,Tm3+和Ho3+为激活离子;Yb3+为敏化离子;x, y, z为分别为Tm3+、Ho3+和Yb3+离子相对Gd3+离子占的摩尔百分比系数,取值范围:0.001≤x≤0.02,0.001≤y≤0.02,0.01≤z≤0.20。
钼酸盐基质发光材料由于其具有良好的化学稳定性和热稳定性,而成为一类比较重要的荧光粉材料。钼酸根MoO4 2-与敏化离子Yb3+ 偶合成MoO4 2--Yb3+二聚物,从而对激活离子Tm3+和Ho3+实现高阶激发态能量传递上转换,降低激活离子中间能级的无辐射弛豫,提高上转换发光效率。
另外,钼酸盐荧光材料生产成本低,烧结温度也比其他磷酸盐、铝酸盐等体系要低,对合成过程中的降低能耗比较有利。
优选地,0.005≤x≤0.01,0.01≤y≤0.04,0.01≤z≤0.20。
上述上转换荧光粉的制备方法,包括将钆盐、钼酸盐、镱盐、钬盐在水中加热,加入柠檬酸,调节pH值,干燥,煅烧,即得所述荧光粉。
溶胶凝胶法具有制备工艺简单,易于操作,设备易得,操作安全,条件容易控制的优点。
优选地,所述制备方法为按化学组成摩尔比,将六水硝酸钆、四水钼酸铵、六水硝酸镱、六水硝酸钬,在水中混合。
优选地,所述煅烧温度为800 ℃~1000 ℃;煅烧时间为1~5小时。
优选地,所述加热温度为60~100℃。
与现有技术相比,本发明具有如下有益效果:
本发明的发光材料采用传统的溶胶凝胶法合成,制备工艺简单,易于操作,设备易得,操作安全,条件容易控制。同时实现了高激发态能量传递上转换,大大提高了上转换效率,所得荧光粉外量子效率高,增强了上转换发光。在照明和显示领域中具有广阔的应用前景。
