Abstract
Optical properties of samarium-doped strontium orthosilicate for near ultra-violet excitation are studied. Sr2SiO4:Sm3+ 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 4G5/2→6H7/2 transition of Sm3+ for near ultra-violet excitation is observed. It is found that Sr2SiO4:Sm3+ is a red-orange emitting phosphor and has higher efficiency for the operation with near ultra-violet excitation.
