Correlations between structural and scintillation characteristics of lead and cadmium tungstates

Temperature dependence of radiation hardness of lead tungstate (PWO) scintillation crystals

“…By studying many PWO crystals with parameters meeting specifications for their use as scintillation crystals in high-energy physics experiments, we observed that decrease of temperature in the range from þ20 C to À20 C results in an increase of light yield approximately by a factor of three irrespectively of its initial value for the crystal, confirming a strong thermal quenching in PWO, as already observed by several authors (Klassen et al, 2002;Novotny et al, 2008). Meanwhile, the radiation hardness of the crystals at lower temperatures is worse than that at room temperature.…”

Photoluminescent Properties of CoMoO<sub>4</sub> Nanorods Quickly Synthesized and Annealed in a Domestic Microwave Oven

“…Materials belonging to the molybdate and tungstate families have a long history of practical applications due to their excellent optical properties in phosphors, laser materials, and scintillation detectors [1][2][3].…”

Mechanisms behind blue, green, and red photoluminescence emissions in CaWO4 and CaMoO4 powders

“…The continuous interest in these compounds lies in their excellent optical properties, which form the basis of their wide use as phosphors, laser materials, and scintillation detectors. [1][2][3] In this work, we evaluated the photoluminescence of two distinct CaMoO 4 ͑CM͒ and CaWO 4 ͑CW͒ powders prepared by the polymeric precursor method, i.e., the crystalline form ͑structurally ordered͒ and the other form ͑structurally disordered͒ before structural order was reached. We also investigated the electronic structure and optical properties using first-principles calculations based on the density functional theory ͑DFT͒.…”
