ErLaP_5O_（14）非晶上转换发光分析

Analysis of Up-conversion Luminescence of ErLaP_5O_(14) Noncrystalline

测量了Ｅｒ０．１Ｌａ０．９Ｏ１４非晶在６４９．０ｎｍ脉冲染料激光泵浦下的上转换荧光谱线（５５２．２，５４５．７，５４２．９）ｎｍ，５２５．０ｎｍ．４６８．８ｎｍ，４５２．２ｎｍ．（４１１．２，４０７．０）ｎｍ，３８４．１ｎｍ．３８０．７ｎｍ，其中（５５２．２，５４５．７，５４２．９）ｎｍ，（４１１．２．４０７．０）ｎｍ．３８４．１ｎｍ话线是共振步进双光子吸收导致的，而４６８．８ｎｍ．４５２．２ｎｍ，３８０．７ｎｍ是三光子荧光。

The up- conversion fluorescence phenomenon of Er0.1La0.9P5O14 noncrystallinepumped by a pulsed dye laser is studied. The peaks of the up-conversion fluorescence are(552.2;545.7;542. 9) um;525.0um;468.8 um;452. 2 um;(411.2;407.0) urn;384.I urn and 380.7 urn. The luminescence(552.2;545.7;542. 9) um;525.0 um;(411.2; 407.0) um and 384.1 um can be ascribed to resonant step by step absorption oftwo phtons by a single ion and 468.8;452.2 and 380.7 um are generated in three--photonprocesses.
