The photoluminescence properties of mono Ce3+ doped Sr5(PO4)2SiO4 (SPS) apatite phosphors, prepared via a solid-state reaction at high temperature, were investigated in the ultraviolet region. The white light can be realized by adjusting the contents of activator Ce3+ or the excitation wavelength. Upon 365 nm excitation, SPS: 0.05Ce3+ shows bright white light (34.74% of YAG) with CIE color coordinates of (0.33, 0.34), a superior color-rendering index of 90 and correlated color temperature of 5603 K, suitable for potential use based on 365 nm UV-InGaN chip.
