| Abstract: | Luminescence properties of Zn WO4:Cr3+ laser crystals were investigated. 4T2 energy level of Cr3+ splitted to three levels, 13550, 14205 and 14706cm-1, and the Stokes-shift of luminescence spectra is 236nm. The best intensity peak of emission is at 912nm. If the excitation wavelength was selected as 608nm and doping concentration was 0.01 wt%, a broad emission band would be observed at 532nm excitation. |
