Characterizations and optical properties of Sm3+-doped Sr2SiO4 phosphors
Source abstract
Abstract
Abstract Optical properties of samarium-doped strontium orthosilicate for near ultra-violet excitation are studied. Sr 2 SiO 4 :Sm 3+ phosphor is synthesized by using the solid-state reaction method. The structure and physical properties of the phosphor are characterized by using X-ray diffractometer, scanning electron microscope, UV–visible spectrophotometer, high-resolution secondary ion mass spectrometer, and X-ray photoelectron spectrometer. Optical properties are 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 is observed. It is found that Sr 2 SiO 4 :Sm 3+ is a red-orange emitting phosphor and has higher efficiency for the operation with near ultra-violet excitation.
