Abstract :
A systematic spectroscopic study of oriented single ZnWO4 crystals was performed using UV and synchrotron excitation. Emission and phosphorescence spectra in the energy region 1–4 eV as well as reflection spectra and excitation spectra of various emissions and phosphorescence in the energy region 3.5–32 eV were studied at 4.2–300 K using synchrotron radiation. The results are compared to those available for CdWO4. The peculiarities of the band structure and those of excitonic and electron–hole processes in the systems investigated are discussed.
