室温条件下测定了Ba(Y1-xCex)2Si3O10(x=0.05,0.07,0.09)的漫反射吸收光谱、光声振幅谱和光声相位谱.由于高浓度掺杂使得Ce3+与Ce3+之间发生有效能量传递,从而导致Ba(Y1-xCex)2Si3O10(x=0.05,0.07,0.09)的漫反射吸收光谱强度依次降低,光声光谱强度依次增大.利用光声振幅谱结合相位谱的方法研究发光效率随掺杂浓度的变化,发现Ba(Y1-xCex)2Si3O10(x=0.05,0.07,0.09)3种不同掺杂浓度试样的发光效率依次降低.
室溫條件下測定瞭Ba(Y1-xCex)2Si3O10(x=0.05,0.07,0.09)的漫反射吸收光譜、光聲振幅譜和光聲相位譜.由于高濃度摻雜使得Ce3+與Ce3+之間髮生有效能量傳遞,從而導緻Ba(Y1-xCex)2Si3O10(x=0.05,0.07,0.09)的漫反射吸收光譜彊度依次降低,光聲光譜彊度依次增大.利用光聲振幅譜結閤相位譜的方法研究髮光效率隨摻雜濃度的變化,髮現Ba(Y1-xCex)2Si3O10(x=0.05,0.07,0.09)3種不同摻雜濃度試樣的髮光效率依次降低.
