激光吸收铒掺杂上转换材料的光谱特性实验分析

Analysis of the spectral properties of Er^(3+):Y_2O_3 upconversion materials

采用湿化学法制备了铒掺杂氧化钇上转换纳米粉体材料.研究了不同掺杂浓度、掺杂元素种类对材料显微结构、物相组成和光谱特性的影响.结果表明,通过控制掺杂元素的种类、掺杂浓度可以实现对光谱性能(包括光谱反射系数和上转换光谱)的调控.实验表明,该材料对1.06μm激光具有较好的吸收性能.

Rare earth doped yttrium oxide（RE^3＋：Y2O3）nano powder was fabricated by wet chemical method.The influence of doping concentration and different doping elements on the microstructure,phase composition and spectral properties was analyzed.It was shown that by changing the doping element and doping concentration,the spectral properties,including spectral coefficients and upconversion spectrum,can be controlled,and the material can be made to have better absorption properties for 1.06 μm laser light.
