Eu2+‐doped AlN—SiC solid‐solution phosphors: Synthesis and cathodoluminescence properties
View through CrossRef
Abstract— Eu and Si co‐doped AlN was reported to be an interesting blue phosphor for field‐emission displays (FEDs). In this paper, SiC instead of Si3N4 was used as the Si source. Eu2+‐doped AlN—SiC phosphors were prepared by firing the powder mixtures of AlN, SiC, and Eu2O3 at 2050°C for 2 hours under 1‐MPa N2. Solid solutions between AlN and SiC were formed in a wide range, promoting the solution of Eu2+ in AlN. The phosphors showed intense blue emissions under electron‐beam excitation, indicative of potential phosphors for FEDs.
