摘要

研究了紫外和x射线激发下CaMoO4单晶和CaMoO4- cawo4混合结构的发光衰减动力学。CaWO4和CaMoO4晶体分别在425 nm和530 nm处有较大的发光带。所有CaMoO4-CaWO4样品在室温下的衰变动力学均表现为非单指数行为。

Oxygen-related defects and luminescence properties of CaMoO4 single crystals and CaMoO4-CaWO4 compounds

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.
