摘要:

The stimulated Raman scattering (SRS) and luminescence spectra of ZnWO4 crystals were investigated using 532 nm laser excitation at room temperature. It was found that the first order (558.7 nm) and second order (588.6 nm) of SRS have 130 and 77 cm(-1) line widths and the pump threshold at 558.7 nm is 6.8 mJ. The luminescence spectrum of ZnWO, crystals under 532 mn laser excitation has the peculiarity of having the band structure composed of three-Gaussian components. The photoluminescence spectrum shows broadband emission from 400 nm to 650 nm peaked about 472.0 nm, which is attributed to the radiative transitions between tungsten and oxygen.
