| 摘 要： | 在特定恒温环境下烧结Er与Yb,Ho与Yb共掺杂氟氧化物两样品。用930nm激光激发，测得两样品的发光射荧光光谱，发现两样品发射荧光光谱中都分别有红光带和绿光带。由Er2O3,Ho2O3,Yb2O3的吸收谱及能级跃迁原理说明了两样品能量上转移机制及特性。

| Abstract: | Er and Yb,Ho and Yb codoped in the oxyfluoride were burnt on in the specific temperature,and got two kinds of samples.Using 930 nm as an exciting light,the emitting fluorescent spectra of two kinds of the samples were measured,and observed the red band and green band fluorescent spectra,respectively.According to the detected absorption spectra of Er 2O 3,Ho 2O 3,Yb 2O 3 and the rule of energy jump,the mechanism and the properties of the energy upconversion of two kinds of the samples were explained.As can be seen,energy upconversion properties were determined mainly by the absorbtion spectra of Er 2O 3,Yb 2O 3.Energy upcoversion efficiency were determined by excitative photons. |
