Abstract
In the present work, Cerium Fluoride (CeF3) was selected as the host material because of its High density, fast response and high radiation resistance, efficient absorption and energy transfer by host (to activator). Rare earths have been used to show the process of Quantum Cutting (QC) via energy transfer process between Tb3+ and Yb3+ incorporated in CeF3. For the synthesis of CeF3 nanoparticles codoped with Tb3+ and Yb3+ ion, co-precipitation route was employed. Different doping concentrations were prepared to study the changes that take place in the luminescence spectra of the composition. Thus, concentration dependent study of the fluorescence of CeF3: Tb3+, Yb3+ was carried out. These materials have great applications in solar cell devices as quantum efficiencies up to 200 % can be achieved.
