ZnWO₄, composed of ZnO and WO₃, is an oxide used in scintillators; it is a self-activated phosphor material that exhibits strong luminescence properties inherent to the crystal itself, without the need for doping with rare-earth ions. In recent years, it has attracted attention as a self-activated luminescent material utilizing emission from self-trapped excitons, exhibiting pale-blue photoluminescence (PL) near 470 nm upon ultraviolet irradiation. Here, we have investigated the compositional dependence of the structure and PL properties of Zn_xW_1-xO_y films fabricated by the pulsed laser deposition (PLD) method.
