Enhanced red emission of NaSrVO4:Eu3+ phosphor via Bi3+co-doping for the application to white LEDs
Source abstract
Abstract
Abstract A series of NaSrVO4:Eu3+ and NaSrVO4:Eu3+, Bi3+ phosphors were synthesized by the combustion method fueled by citric acid. The structure and photoluminescence properties of the phosphors were examined by X-ray powder diffraction (XRD) scanning electron microscope (SEM) and photoluminescence spectroscopy (PL). The samples are well crystallized in the monoclinic phase with the P21/n space group. According to the photoluminescence spectra, the phosphors are efficiently excited by near-UV light and exhibited a bright red emission centered at ~625 nm. The photoluminescence intensities of the NaSrVO4:Eu3+, Bi3+ phosphors are significantly enhanced by the efficient energy transfer between Bi3+ and Eu3+. The emission intensity of NaSrVO4 is maximized by co-doping with 15 mol% Eu3+ and 3 mol% Bi3+. The sensitization mechanism was also deduced from energy level diagrams of the Eu3+ and Bi3+ ions.
