氟氧化物玻璃中稀土ErYb与HoYb能量上转换特性研究

Studies on the Properties of Energy Upconversion of the Rare Earth ErYb and HoYb in the Oxyfluoride Glass

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Er2 O3 ,Ho2 O3 ,Yb2 O3

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 Er2O3, Ho2O3, Yb2O3 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 Er2O3, Yb2O3. Energy upcoversion efficiency were determined by excitative photons.
