实验给出了掺Er3+ ∶Mg Al尖晶石晶体的吸收谱、荧光谱和激发谱 ,确定了Er3+ 离子在Mg Al尖晶石晶体中的能级位置。用Judd Ofelt理论计算得到了掺Er3+ ∶Mg Al尖晶石晶体的光谱特性参数。最后对该掺杂晶体出光的可能性进行了分析。
The absorption spectra, fluorescence spectra and excitation spectra of Er3 +: MgAl spinel crystals were given experimentally, and the energy level positions of Er3 + ions in MgAl spinel crystals were determined. The spectral characteristic parameters of Er3 +: MgAl spinel crystals were calculated by Judd Ofelt theory. Finally, the possibility of light out of the doped crystal was analyzed.
