Precipitation and re-precipitation of metal ions has been carried out from original and supernatant solution producing Bi<SUP>3+</SUP> - Eu<SUP>3+</SUP> doped Y<SUB>2</SUB>O<SUB>3</SUB>:Eu<SUP>3+&l...
Precipitation and re-precipitation of metal ions has been carried out from original and supernatant solution producing Bi<SUP>3+</SUP> - Eu<SUP>3+</SUP> doped Y<SUB>2</SUB>O<SUB>3</SUB>:Eu<SUP>3+</SUP> and Eu<SUP>3+</SUP>/Tb<SUP>3+</SUP> doped Y<SUB>2</SUB>O<SUB>3</SUB>, respectively. Shorter reaction time is unable to consume all metal ions present in the solution which can be utilized through re-precipitation process. The doping of Bi<SUP>3+</SUP> - Eu<SUP>3+</SUP> in Y<SUB>2</SUB>O<SUB>3</SUB> helps to absorb maximum UV light. The activation of Y<SUB>2</SUB>O<SUB>3</SUB> matrix by Bi<SUP>3+</SUP> and Eu<SUP>3+</SUP> ions, together and separately, were studied considering the excitation energy transfer to the luminescence centers. The successful replacement of Y<SUP>3+</SUP> by RE<SUP>3+</SUP> ions can help for fine tuning of emission wavelength. Re-precipitation of supernatant solution by adding terbium precursor can successively produce uniform sized Tb<SUP>3+</SUP> doped Y<SUB>2</SUB>O<SUB>3</SUB>:Eu<SUP>3+</SUP>. The re-precipitation of the supernatant solution ensures maximum consumption of metal ions for higher product yield and possible fine tuning of emission wavelengths.
