摘要
用高温熔融法制备了不同Er3+浓度掺杂的SiO2-Al2O3-CdO-Li2O-K2O-Na2O玻璃样品,测试了其吸收光谱和发射光谱。研究结果表明:在365nm激发下,玻璃样品发射绿光,发射峰强度随着Er3+浓度的增加具有先增加再减小,最后快速增长的关系;在488nm激发下,样品除发射绿光外,还发射较强的731nm红光,且Er3+掺杂浓度为0.2mol和0.4mol时,其发射峰值强度基本相同;可以通过调整Er3+掺杂浓度,进而获得高强度荧光发射。
The glass samples of SiO2-Al2O3-CdO-Li2O-K2O-Na2O with different Er3+-doped concentration are fabricated by high-temperature solid-state reaction method,and the absorption spectra as well as emission spectra are tested.The results indicate that when the glass samples are excitated at 365 nm laser with emitting green light,the intensities of the emission peaks along with the enhancement of the Er3+-doped concentration increase firstly,then decrease,and finally go up.And when the glass samples are excitated at 488 nm laser with emitting red green of 713 nm besides green light,the intensities of the emission peaks are almost the same when the Er3+-doped concentration is 0.2 mol and 0.4 mol.We can obtain high-intensity fluorescent emission by adjusting the Er3+-doped concentration.
