Nanoparticles and nanoribbons of SbPO4 and lanthanide ions
(Eu3+, Ce3+ and Tb3+) doped SbPO4 were prepared at a low temperature of 120
°C by co-precipitation method in solvents like ethylene glycol and glycerol. By varying the relative ratios of the two solvents, average crystallite size of
SbPO4 has been varied over a range of 12 to 46 nm. Based on steady state luminescence studies, existence of energy transfer between host
SbPO4 and lanthanide ions has been confirmed. Co-doping
SbPO4:Tb3+ nanoparticles/nanoribbons with Ce3+, resulted in improved luminescence
due to energy transfer from Ce3+ to Tb3+ ions. Further, these nanomaterials can be incorporated in sol–gel derived silica glass without any deterioration of their luminescence properties. Present study offers a viable method for preparing composite luminescent materials based on nanoparticles/nanoribbons and glasses.
