Synthesis and Luminescence Properties of Pomponlike CaMoO₄:Eu³⁺ Red Phosphors by Hydrothermal Method

Abstract

The pomponlike CaMoO4:Eu3+ red phosphors were synthesized via a ethylene glycol (EG)-mediated hydrothermal method in the presence of urea at 140 °C for 1 h. The structure, morphology and luminescent property were characterized and investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and photoluminescence (PL). The results show that the Eu3+-doped CaMoO4 micropompons were well-crystallized and assembled by nanosheets. The products display a strong red emission under near ultraviolet (UV).
