摘要：

In this work, KZnPO4:Dy3+ and KZnPO4:Sm3+ phosphors are synthesized using the Combustion technique. The phosphor XRD and photoluminescence properties were studied. The XRD was used to confirm the orthorhombic phase with the space group P n a 21. The PL emission spectra of the synthesized KZnPO4:Dy3+ phosphor shows a strong emission at 482 and 574 nm under 350 nm excitation, which is ascribed due to F-4(9/2)& RARR;H-6(15/2) and F-4(9/2)& RARR;H-6(13/2) electronic transitions of the Dy3+ ions, respectively. When the KZnPO4:Sm3+ phosphor was excited at 402 nm, the emission spectra exhibited prominent bands located at 562 and 597 nm. The CIE coordinates show that the current phosphors have high colour purity. The KZnPO4:Dy3+ and Sm3+ phosphors provide an excellent candidate for n-UV-based w-LEDs.
