Bright emission via energy transfer from Dy to Tb in Bi2SiO5 nanophosphor
Source abstract
Abstract
Abstract The present article discusses the optical and structural properties of Tb and Dy co-doped Bi2SiO5 nanophosphors which were synthesized by Co-precipitation method. The synthesized sample contains plate-like morphology of uniform thickness ∼200 nm. Prepared samples were found of average crystallite size ∼20 nm, which yield bright yellow dominating white emission and green emission, in Dy: Bi2SiO5 and Tb: Bi2SiO5 nanophosphor, respectively under UV-light excitation. We have reported one-way efficient energy transfer from Dy to Tb ion, which facilitates precise colour tuning ability. The energy transfer phenomenon was well explored using, photoexcitation, photoluminescence and time-resolved luminescence techniques.
