Abstract :
Emission spectra under UV and X-ray excitations, as well as luminescence decay kinetics of CaMoO4 single crystals and CaMoO4-CaWO4 mixed structures were studied. The broad luminescence bands with maxima at 425 and 530 nm correspond to CaWO4 and CaMoO4 crystals, respectively. The decay kinetics show non-single exponential behavior for all investigated CaMoO4-CaWO4 samples at room temperature.
