摘要: The synthesis, composition optimization, VUV Photoluminescence (PL) spectra, and optical properties, of (Y, Gd) (V, P)O-4 : Eu3+ phosphors were investigated by synchrotron radiation. The VUV PLE spectra and the correlation among VUV PL intensity, lambda(em), and Eu3+, Gd3+, and P-content were established. The PLE spectral studies showed that (Y, Gd) (V, P)O-4: Eu3+ exhibited significant absorption in the VUV range. The VUV PL intensity was found to enhance with PO43- and Gd3+ -doping. Furthermore, the chromaticity characteristics of (Y, Gd) (V, P)O-4: Eu3+ were also found to be (0.6614, 0.3286) and compared against (Y, Gd)BO3:Eu3+ as a reference. Based on the characterization results, we are currently improving and evaluating the potential application of (Y, Gd) (V, P)O-4: Eu3+ as a new red-emitting PDP phosphor.
