Description

Pr3+ (1-11 mol%) rare earth doped Mg2SiO4 (Forsterite) nanophosphors were analyzed using Judd-Ofelt theory for the electronic transitions of Pr3+ ions to evaluate various intensity parameters (Ω2, Ω4). The variations in radiative transition probability (AT) and calculated radiative lifetime (τrad) have been discussed. Further, energy transfer from the host to Pr3+ ions was studied. The critical energy transfer distance (Rc) between Pr3+ ions in Mg2SiO4:Pr3+ phosphor is calculated to be 16.3 Å. The interaction between the Pr3+ ions is found to be dipole-dipole interaction.
