Spectroscopic investigation of La7Ta3W4O30:Sm3+ orange-red phosphor for white LEDs
The novel orange-red light emitting La7Ta3W4O30:xSm3+ (x = 0.005–0.20) phosphors were synthesized via the solid-state reaction method. The crystal structure, photoluminescence (PL) properties, optimum concentration, color purity, decay life, and thermal stability of the samples were systematically s...
