Abstract

A new self-activated X-ray scintillator, BaWO₂F₄, with an excellent photoluminescence quantum efficiency is reported. Hydrothermally grown single crystals, space group P2/n, exhibit a 3D framework structure containing isolated WO₂F₄ octahedra. BaWO₂F₄ exhibits green emission under UV light with a high quantum yield of 53% and scintillates when exposed to X-rays(Cu).
