Undoped and Tb3+ doped YBO3 and Y3BO6 were prepared by co-precipitation method in ethylene glycol medium at 100°C followed by annealing at 800°C. The spin allowed 4f8→4f75d1 (low spin) and spin forbidden 4f8→4f75d1 (high spin) transitions of Tb3+ are well resolved in YBO3 host as compared to Y3BO6. This has been attributed to difference in the distribution of local environment around Y3+/Tb3+ in these...
Very small nanoparticles (size 3–5nm) of Y 2 Sn 2 O 7 , Y 2 Sn 2 O 7 :Tb 3+ and Sb 3+ co-doped Y 2 Sn 2 O 7 :Tb 3+ were prepared at a relatively low temperature of 700°C. Y 2 Sn 2 O 7 host is characterised by an emission around 436nm, which is arising from the oxygen vacancies present...
