Abstract

In this article, we report the synthesis of Na2 Sr1-x (PO4)F:Eux phosphor via a combustion method. The influence of different annealing temperatures on the photoluminescence properties was investigated. The phosphor was excited at both 254 and 393 nm. Na2 Sr1-x (PO4)F:Eux (3+) phosphors emit strong orange and red color at 593 and 612 nm, respectively, under both excitation wavelengths. Na2 Sr1-x (PO4)F:Eux (3+) phosphors annealed at 1050°C showed stronger emission intensity compared with 600, 900 and 1200°C. Moreover, Na2 Sr1-x (PO4)F:Eux (3+) phosphor was found to be more intense when compared with commercial Y2 O3:Eu(3+) phosphor.

摘要

本文通过燃烧法合成了 Na2 Sr1-x (PO4)F:Eux 荧光粉，并研究了不同退火温度对其光致发光性能的影响。该荧光粉分别在 254nm 和 393nm 波长下被激发，发射出分别位于 593nm 和 612nm 的强橙色和红色光。在 1050°C 下退火的 Na2 Sr1-x (PO4)F:Eux (3+) 荧光粉的发射强度比在 600°C、900°C 和 1200°C 下退火的要强。此外，与商用 Y2 O3:Eu(3+) 荧光粉相比，Na2 Sr1-x (PO4)F:Eux (3+) 荧光粉的强度更高。
