Abstract

A new Ce³⁺-doped oxyfluorosulfide phosphor, Y₃OF ₃S₂:Ce³⁺, has been investigated as a new candidate for potential application in phosphor-converted light emitting diodes (pc-LEDs). The synthesized Y₃OF₃S₂:Ce ³⁺ was characterized by powder X-ray diffraction and various spectroscopic techniques. Y₃OF₃S₂:Ce ³⁺ can be excited by wide-range (250-400 nm) radiation and shows yellow-orange broadband emission peaking at 610 nm with a quantum efficiency of 40%. These results indicate it may serve as a promising phosphor in near-UV pc-LEDs.
