主 题:rare earth phosphates combustion optical materials luminescence chromaticity
摘 要:Rare earth doped materials are an important type of phosphors due to their excellent performance such as stability at high temperature and light emission covering the entire visible domain. The combustion synthesis at acid pH of the monoclinic LaPO4: Eu(5%) powders was described. A mixture of La(NO3)3·6H2O, EuCly6H2O and (NH4)2HPO4 was used as anion precursor and glycin as fuel. The synthesis was followed by structure, morphology characterisation and luminescent properties of the obtained compound. The room temperature emission measurements under ultraviolet excitation at 254 nm were made for the emission transition ^5D0→^7FJ of this phosphor. The CIE (Commission Intemationale de L'Eclairage) chromatic coordinates, dominant wavelength and colour purity were determined and compared to other luminescent materials obtained by other methods.
