利用一种简单有效的水热-后煅烧方法合成了Sr5(PO4)3Cl∶Ce3+磷光体。实验结果表明,通过调节水热条件的溶剂类型和组成可以得到球形/橄榄球形Sr5(PO4)3Cl∶Ce3+磷光体。橄榄球形Sr5(PO4)3Cl∶Ce3+磷光体的内在生长方向为[001],空间群为P63/m。更为重要的是,可以利用后煅烧方法来研究Sr5(PO4)3Cl∶Ce3+磷光体的光学性能,发光强度的主要影响因素包括Ce3+含量、煅烧温度、H2O-三乙醇胺体系中的体积比。Sr5(PO4)3Cl∶Ce3+磷光体的发光谱以及CIE色温图表明,该产物具有蓝光发射的特性。
Sr5 (PO4) 3Cl: Ce3 + phosphor was synthesized by a simple and effective hydrothermal-after calcination method. The experimental results show that the spherical / rugby-shaped Sr5 (PO4) 3Cl: Ce3 + phosphor can be obtained by adjusting the solvent type and composition of hydrothermal conditions. Rugby Sr5 (PO4) 3Cl: Ce3 + phosphor has an intrinsic growth direction of [001] and a space group of P63 / m. More importantly, the optical properties of Sr5 (PO4) 3Cl: Ce3 + phosphors can be studied by the post-calcination method. The main influencing factors of luminescence intensity include Ce3 + content, calcination temperature and volume ratio in H2O-triethanolamine system. The emission spectrum of Sr5 (PO4) 3Cl: Ce3 + phosphor and the CIE color temperature profile show that the product has blue emission characteristics.
