Abstract: Rare earth doped materials are an important type of phosphors due to their excellent performance such as stability at high tem-perature and light emission covering the entire visible domain. The combustion synthesis at acid pH of the monoclinic LaPO4: Eu(5%) pow-sis 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 Internationale de L'Eclairage) chromatic coordinates, dominant wavelength and colour purity were determined and compared to other luminescent materials obtained by other methods.
