英文摘要: This paper reports the photoluminescence (PL) properties of nanocrystalline YVO4: Tot phosphor synthesized by the polymerizable complex method based on the Pechini-type reaction. The powder was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), absorption spectroscopy and PL. The results of XRD and TEM show that, high-quality nanopowders with controlled morphology and microstructure were prepared at a relatively low temperature about 700 degreesC. Upon ultra violet excitation the vanadate host transferred energy to thulium ions efficiently and strong blue emission (475 nm) assigned to (1)G(4)-->H-3(6) transmission is observed. By analyzing excitation and emission spectra of thulium doped yttrium vanadate, we deduced the mechanism of the energy transfer between vanadate host and thulium ions. (C) 2004 Elsevier Ltd.
