研究Cr3+离子掺杂固体物质的制备工艺以及光谱特性有助于开发新的光学材料.本研究分别用提拉法技术生长了Cr3+∶BeAl2O4晶体, 用坩埚下降法技术生长了Cr3+∶LiNbO3晶体, 以及用高温熔融法技术研制了ZnO-Al2O3-SiO2微晶玻璃.获得了生长优质Cr3+∶BeAl2O4与Cr3+∶LiNbO3的工艺参数.分别测定与讨论了Cr3+离子在上述不同介质中的吸收光谱与荧光光谱特征.实验发现Cr3+离子在不同介质中, 其吸收光谱与荧光光谱的位置与形状在不同基质中发生很大的差异.在Cr3+∶BeAl2O4与Cr3+∶LiNbO3晶体中均观测到尖锐的R线荧光.从其相应的光谱特性大致估算了Cr3+离子在不同介质中的晶格场参数.从Dq/B值数据判断Cr3+∶BeAl2O4与Cr3+∶LiNbO3晶体属于强晶格场, Cr3+∶ZnO-Al2O3-SiO2与其微晶玻璃属于弱晶格场.
