| 摘 要： | 本文报道了掺钕氟化物玻璃在８５８ｎｍ半导体激光激发下的上转换发光。在观测到的各条条谱线中,与三光子过程相联系的绿光发射在强度上占绝对优势,表明钕离子在合适的氟化物玻璃有可能成为有效的绿光发射的上转换材料。

| Abstract: | In this paper,we report the upconversion luminescence of Nd:fluoride glasses pumped with 858 nm diode laser.Among the observed upconversion spectra,the green emisson concerning with three photon process has overwhelming superiority in intentisty,when the doping concentration of Nd 3+ is enhanced,the green upconverion emission increases more drastically than that of other upconverted emissions.The experiment results indicate that fluoride glasses doped with Nd 3+ posssses possibility of being green emitting upconversion materials.When the upconversion mechanism is discussed,the green luminescence concerning with three photon is ascribed to three ion cooperative upconversion |
