摘要

本文利用化学燃烧合成法制备了Al_2O3:Eu

Al_2O3:Tb和Al_2O3:Eu:Tb陶瓷粉末

研究了退火温度和掺杂浓度对稀土元素掺杂Al_2O3陶瓷粉末光致发光性能的影响.结果表明:采用Al(NO3)3、Eu(NO3)3、Tb(NO3)3为原料制备的Al_2O3:Eu

Al_2O3:Tb陶瓷粉末

其样品随着退火温度的不断升高

发光强度先增强再减弱

光致发光峰位没有发生变化

并且最佳的退火温度分别是900?C、1100?C.随着稀土元素掺杂浓度的不断增大

样品光致发光强度先增强再减弱

最佳的掺杂浓度分别是0.055mol%、0.02mol%.在制备Al_2O3:Tb:Eu陶瓷粉末时

只改变Tb3+离子的掺杂浓度而保持Eu3+离子的掺杂浓度是0.04mol%固定不变.随着Tb3+离子掺杂浓度的增大

Eu3+离子处于592nm

618nm

653nm

705nm的光致发光峰强度增加

而Tb3+离子在545nm处的光致发光峰强度却随着Tb3+离子掺杂浓度从0.14mol%增大到0.17mol%逐渐减小.此研究可为改善和提高Al_2O3基陶瓷材料的发光性能提供一定的实验依据.

Abstract

Al_2O3: Eu

Al_2O3: Tb and Al_2O3: Eu: Tb ceramic powders are prepared by chemical combustion synthesis method and the effect of doping concentration and annealing temperature of the Al_2O3 ceramic powder doped with rare earth element on the photoluminescence properties are studied in this paper.The results show that the luminescence intensity of the Al_2O3: Eu

Al_2O3: Tb ceramic powder which are made with aluminum nitrate

europium nitrate and terbium nitrate as raw materials increases first and then decreases and the photoluminescence peak position does not change with the increase of the sample annealing temperature

and the optimum annealing temperature is 900?C and 1100?C

respectively. With the increase of doping concentration of the rare earth element Eu or Tb

the luminescence intensity increases first and then decreases

and the optimum doping concentration are 0.055 mol% and 0.02 mol%

respectively. In preparation of Al_2O3: Tb: Eu ceramic powders

Eu3+ions concentration are kept at 0.04 mol% and Tb3+ concentrations are varied. The results show that the photoluminescence peak intensity of Eu3+ ions at 592 nm

618 nm

653 nm and 705 nm increases with the increase of the Tb3+ ions concentration

while the emission peak intensity of Tb3+ ions at 545 nm gradually decreases with the increase of Tb3+ ions concentration from0.14 mol% to 0.17 mol% This study can provide an experimental basis for improving the photoluminescence characteristics of Al_2O3-based ceramic materials.
