Er3+/Sm3+- and Tb3+/Sm3+-doped glass phosphors for application in warm white light-emitting diode
Source abstract
Abstract
Abstract Tunable polychromatic light emission within the low correlated color temperature range was produced using terbium- and/or erbium–samarium co-doped PbGeO 3 :PbF 2 :CdF 2 glass phosphor. The phosphors were synthesized, and their luminescence characteristics were examined under UV–blue light-emitting-diode laser excitation. Luminescence emissions around 490, 545, 600, and 645 nm in Tb 3 + /Sm 3 + co-doped phosphor and 525, 545, 600, and 645 nm in Er 3 + /Sm 3 + co-doped phosphor were obtained and analyzed as a function of the active ion concentration and excitation wavelength. Color tunability in the red–orange–yellow–green region was achieved combining the Tb 3 + , Er 3 + , and Sm 3 + active ion contents. Results suggest that the color-tunable polychromatic light emitter herein reported is a promising candidate for application in warm white-light emission.
