【摘要】 本文首次研究了掺铒氟（卤）磷碲酸盐玻璃的吸收光谱和上转换荧光光谱,探讨了Er³⁺往氟（卤）磷碲酸盐玻璃中的上转换发光机理。在975nm 激光二极管抽运下产生强烈的上转换红光及绿光,且红光的发光强度要远远大于绿光。以PbCl₂取代PbF₂后,红光的发光强度下降,而绿光却没有明显变化:以ZnCl₂取代ZnF₂达5mol%时,红光和绿光的发光强度均明显增大。更多还原

【Abstract】 The absorption and upconversion spectra of Er³⁺-doped fluoride（halide）phosphate tellurite glasses were investigated for the first time,and the upconversion mechanisms were studied.Stronger red and green upconversion luminescence were tested under 975nm laser diode excitation at room temperatureWhen PbF₂ is replace by PbCl₂ gradually,the intensity of red emission decreases,while green emissionintensity changes slightly.If ZnF2 is replaced by 5mo1% ZnCl₂,both red and green emissions intensityenhanced obviously.更多还原
