| Abstract: | Eu3+ and Sm3+single-doped yttrium vanadate phosphors are prepared by the combustion synthesis respectively using citric acid and urea as fuels.The pyrolysis characteristic of the precursor is analyzed by differential scanning calorimetry(DSC),and the uniformity of phase,surface morphology,excitation spectra and emission spectra of the obtained samples are characterized by X-ray diffractometer(XRD),scanning electron microscopy(SEM)and fluo-rescence spectrophotometer respectively.The experimental results show... |
