Excited states of molybdenum oxyanion in scheelite and wolframite structures

Scheelite CdMoO4CdMoO4 and wolframite CdWO4CdWO4:Mo (0.04–0.4 wt%) single crystals were studied using the time-resolved spectroscopy under UV excitation over a temperature range of 1.85–300 K. The threshold energies for the creation of free charge carriers were measured using the method of photostimulated luminescence. The decay kinetics of the main emission in CdMoO4CdMoO4 and the molybdenum-related emission in CdWO4CdWO4:Mo was studied and the parameters of the triplet excited states of molybdenum-related oxyanions were calculated.
