Luminescence Properties of ZnWO4:Cr3+ Laser Crystals

摘要

Luminescence properties of Zn WO4 : Cr(3+) laser crystals were investigated.(4)T2 energy level of Cr(3+) splitted to three levels, 13550, 14205 and 14706/cm, and the Stokes shift of luminescence spectra is 236 nm. The best intensity peak of emission is at 912nm. If the excitation wavelength was selected as 608 nm and doping concentration was 0.01 wt%, a broad emission band would be observed at 532 nm excitation. jg p.4.
