Abstract

An efficient green-emitting La₆Si₄S₁₇:Ce³⁺ phosphor was synthesized using a solid-state method. The phosphor exhibits a triclinic structure as the main phase. A broad green emission is observed upon excitation at 420 nm with a quantum efficiency of 83%. A white LED fabricated with the phosphor is promising for use in solid-state lighting applications.
