研究了 GeO2-Li2O-Er2O3 玻璃的结构和光学性能。结果表明，Er3+掺杂的锗酸盐玻璃的声子能量随着Li2O含量的增加而降低，但上转换和近红外发光强度却降低。分析认为主要是由于OH−基团（约3100~3500 cm−1）对Er3+上转换发光的影响大于声子能量，且OH−基团对近红外发光影响较大。
The structures and optical properties of GeO2–Li2O–Er2O3glasses are investigated. The results indicate that the phonon energy of Er3 +-doped germanate glasses is decreases with the increasing in Li2O content, but the upconversion and near infrared luminescence intensity is decreases. The analysis considers that it is attributed mainly to the effect of OH−group (about 3100–3500 cm− 1) on the upconversion luminescence of Er3 +was bigger than that of the phonon energy, and also the OH−group strongly influence the NIR luminescence.
