Abstract

•Solution combustion synthesis of YAlO3:Mn phosphor and ceramics preparation.•An efficient YAP:Mn2+ phosphor with green emission at 530 nm.•The phosphor is applicable for thermoluminescent dosimetry of ionizing radiation.

The work describes results of Mn-doped YAlO3 (YAP) nanocrystalline materials synthesized by the solution combustion method using urea as a fuel. The materials were characterized by X-ray powder diffraction, scanning electron microscopy and luminescence techniques. The combustion synthesis method with codoping with Hf4+ ions allows to obtain highly efficient YAP:Mn2+ phosphor with negligible emission from Mn4+ ions that can be applicable for thermoluminescent dosimetry of ionizing radiation. Namely, the phosphor has a single dominating thermal glow peak at about 200 °C with the green emission near 530 nm related to Mn2+(Y) ions.
