稀土掺杂YPO_4发光材料表征与性能及获得特种材料的方法
|
摘要
采用水热法,以氯化钇、柠檬酸钠、磷酸钠等为基体合成1μm左右的YPO_4发光基质材料,将Ce~(3+)、Tb~(3+)等离子掺杂其中得到下转换发光材料.通过研究反应温度、反应时间、掺杂比和烧结温度等因素对发光性能的影响,获得了在紫外光的激发下发出强光的稀土下转换发光材料,并通过改变Tb3+掺杂浓度得出对YPO_4:Ce~(3+),Tb~(3+)发光性能及寿命的影响,最终在反应时间为24 h、溶液pH为3时得到了形貌规则的四方相纳米材料,当Tb~(3+)浓度为1%时发出较强的绿光.
In this paper, by using hydrothermal method, with yttrium chloride sodium citrate and sodium phosphate as matrix to synthesize about 1 μm YPO4 luminescent host material, then doping Ce~(3+) and Tb~(3+) plasma to acquire down conversion luminescent properties. Through the study of reaction temperature, reaction time, doping ratio and sintering temperature and other factors on the performance of light-emitting ratio, we obtain light emitting rare earth conversion luminescent materials under the excitation of ultraviolet light, and conclude the influence of YPO_4: Ce~(3+), Tb~(3+) on the luminescent properties and luminescent life by changing the Tb~(3+) doping concentration. Finally, the tetragonal nanomaterials with regular morphology are obtained when the reaction time is 24 h and pH of the solution is 3, and strong green light is emitted when the concentration of Tb~(3+) is 1%.
