Significantly enhanced photoluminescence and thermal stability of La(3)Si(8)N(11)O(4):Ce(3+),Tb(3+)via the Ce(3+) → Tb(3+) energy transfer: a blue-green phosphor for ultraviolet LEDs
A series of Ce(3+)-, Tb(3+)- and Ce(3+)/Tb(3+)-doped La(3)Si(8)N(11)O(4) phosphors were synthesized by gas-pressure sintering (GPS). The energy transfer between Ce(3+) and Tb(3+) occurred in the co-doped samples, leading to a tunable emission color from blue to green under the 360 nm excitation. The...
