摘　　要：采用中温水热法合成了立方钙钛矿单相 KZn F3 及 KZn F3 ∶ Eu,通过 SEM观察了产物形态 ;XPS测定结果表明 ,产物含氧量不高 ;荧光光谱及 ESR谱表明 ,KZn F3 ∶ Eu体系中 Eu2 +与 Eu3 +共存 。The polycrystals of KZnF 3∶Eu have been synthesized by hydrothermal method at 220 ℃. The product was characterized by XRD, XPS and SEM. The emission and excitation spectra of europium ion were measured. The existence of Eu 2+ ion was confirmed by ESR and spectroscopy. The sites were possibly occupied by Eu 2+ ions, charge compensation in this crystal were also discussed. [WT5HZ]
