Synthesis, Composition Optimization, and VUV Photoluminescence Characterization of (Y, Gd) (V, P)O4: Eu3+ as A Potential Red-Emitting Plasma-Display Panel Phosphor
The synthesis, composition optimization, VUV Photoluminescence (PL) spectra, and optical properties, of (Y, Gd)(V,P)O<,4>: Eu<3+> phosphors were investigated by synchrotron radiation. The VUV PLE spectra and the correlation among VUV PL intensity, λ<,em>, and Eu<3+>, Gd<3+>, and P-content were established. The PLE spectral studies showed that (Y, Gd) (V,P)O<,4>: Eu<3+> exhibited significant absorption in the VUV range. The VUV PL intensity was found to enhance with PO<,4> <3-> and Gd<3+>-doping. Furthermore, the chromaticity characteristics of (Y, Gd)(V, P)O<,4>: Eu<3+> were also found to be (0.6614, 0. 3286) and compared against (Y, Gd)BO<,3>: Eu <3+> as a reference. Based on the characterization results, we are currently improving and evaluating the potential application of (Y, Gd)(V, P)O<,4>: Eu<3+> as a new red-emitting PDP phosphor.
