Abstract

Abstract Red emitting Li2CaSnO4: xEu3+ phosphors were successfully synthesized by the high-temperature solid-state method. The crystal structure, composite and luminescence properties (e.g. the excitation and emission spectra, fluorescent lifetimes, and CIE chromaticity coordinates) of the samples were investigated by X-ray diffraction (XRD), high-resolution transmission electron microscope (HRTEM), energy dispersive spectrometer (EDS) and spectral analysis technique. The emission spectra consist of the characteristic peak resultant to Eu3+ under the excitation of 395 nm and the dominant emission peak is at 621 nm (7F0→5L6). The optimal red emission was obtained through 4% Eu3+ doping. These new red Li2CaSnO4: Eu3+ phosphors have the potential application for white LEDs.
