White light emission from single-phase Y2MoO6: xPr3+ (x = 1, 2, 3 and 4 mol%) phosphor

A series of Pr3+ doped with Y2MoO6 was synthesized using the co-precipitation method and the structural, photoluminescent and morphological properties of XRD, scanning electron microscopy (SEM) and photoluminescence spectrometry were investigated. The most intense absorption of its host matrix occurred between 200 and 340 nm due to a charge transfer in O → Mo. The photoluminescence emission results of Y2MoO6: x%Pr3+particles showed some white emission due to a strong contribution of the matrix and the Pr3+dopant. All samples exhibited high color rendering index (>90%), indicating that the light source can reproduce colors. It was possible to obtain a white-emitting single-phase luminescent material from an easy route of production. The investigation indicated that Y2MoO6: x%Pr3+ is a potential candidate for applications with white light emitting diodes.
