LiCaAlN2:Eu3+/Tb3+ red/green phosphors were successfully prepared by conventional solid‐state reaction. The photoluminescence (PL) properties and cathodoluminescence (CL) properties of LiCaAlN2:Eu3+/Tb3+ were investigated in detail. The Eu3+ (Tb3+) doped LiCaAlN2 shows red (green) emission peaking at 615 nm (550 nm). Monitored at 615 nm (550 nm), it is interesting to found that LiCaAlN2:Eu3+ (LiCaAlN2:Tb3+) has a broad charge transfer transition in the range of 350‐450 nm (275‐375 nm) peaking at 380 nm (343 nm), which can be efficiently excited by n‐UV light‐emitting diodes (LEDs). Under electron beam excitation, LiCaAlN2:Tb3+ exhibited a good resistance to the current saturation. The white LED has also been fabricated with blue, green, and LiCaAlN2:Eu3+ red phosphor. The results indicate that LiCaAlN2:Eu3+/Tb3+ could be conducive to the development of phosphor‐converted LEDs and field emission displays (FEDs).
