摘　　要：制备了一种新型的组分为12Na2O-23La2O3-65Ga2O3(NLG)的镓酸盐玻璃,以共掺杂Tm3+和Yb3+离子作为上转换研究对象,研究了该玻璃系统的光谱性质.在980nm半导体激光器激发下,观察到强的蓝色(478nm)、红色(652nm)和近红外光(805nm)的上转换发光.研究了上转换发光强度与激发光功率的关系,并讨论了相应的上转换发光机理.The optical properties of Tm^3＋/Yb^3＋ Co-doped alkali lanthanum gallate glasses （12Na2O-23La2O3-65Ga2O3） were investigated under an excitation from a commercially available 980 nm laser diode. Blue （478 nm）, red （651 nm） and near infrared （NIR） emission bands were observed which were corresponding to the transitions of ^1G4→^3H6, ^1G4→^3 F4 and ^3H4→^3H6 of Tm^3＋ ions, respectively. The upconversion intensity dependence of excitation power and possible upconversion mechanism were evaluated.
