· JVASP-46401· DyWO4

Dysprosium tungstate (DyWO4) is a rare-earth ceramic compound belonging to the tungstate family, valued for its optical and thermal properties in specialized applications. It is primarily used in scintillation detectors, phosphor materials, and high-temperature optical systems where its luminescence characteristics and chemical stability are advantageous. This material is particularly noteworthy in nuclear radiation detection and medical imaging contexts, where alternatives like yttrium tungstate or cadmium tungstate may have limitations in scintillation efficiency or environmental compatibility.
