Sm3+-doped CaTiO3 phosphor: Synthesis, structure, and photoluminescent properties
Source abstract
Abstract
Abstract Photoluminescent properties of samarium-doped calcium titanate for near ultra-violet excitation were studied. CaTiO 3 :Sm 3+ phosphor was synthesized by using the solid-state reaction method. The structure and properties of the phosphor were characterized by using X-ray diffractometer, scanning electron microscope, UV–visible spectrophotometer, high-resolution secondary ion mass spectrometer, and X-ray photoelectron spectrometer. The photoluminescent properties were studied by taking excitation and emission spectra. A strong red–orange luminescence corresponding to 4 G 5/2 → 6 H 7/2 transition of Sm 3+ for near ultra-violet excitation was observed. It was found that CaTiO 3 :Sm 3+ was a red–orange emitting phosphor and had higher efficiency for the operation with near ultra-violet excitation.
