摘要:
通过高温固相法合成了Ho3+-Yb3+共掺杂La2O3上转换荧光粉. 在980、1 064以及800 nm 3种不同波长的激光激发下,样品产生了明显的上转换荧光.利用980 nm的激光作为激发源, 在Ho3+掺杂量为0.5%的条件下,研究了Yb3+掺杂量的变化对样品上转换荧光强度的影响.研究结果表明:Yb3+掺杂浓度为10%样品产生的上转换荧光最强,相比未掺Yb3+的样品,绿光强度提高了65倍,对样品的上转换发光机理进行了详细的研究.
Abstract:
Ho3+-Yb3+ codoped La2O3 upconversion phosphor is synthesized by high-temperature solid-state method.Under excitation of 980,1 064 and 800 nm laser,obvious upconversion luminescence is observed in the samples.With 980 nm laser as excitation source,the effect of Yb3+ concentration on upconversion luminescence intensity of the samples is studied when Ho3+-doped concentration is kept at 0.5%.The result shows that the sample doped with 10% Yb3+ has the strongest upconversion luminescence,and the green light intensity is increased by 65 compared to the sample without Yb3+.The upconversion luminescence mechanism of the samples is investigated in detail.
