Abstract: A study of Non-radiative energy transfer in UO2-Ho system in zinc phosphate glass has been done by observing the steady state emission of UO2++ with varying concentration of Ho3+ in zinc phosphate glass at room temperature. It has been observed that UO2++ ion emission intensity decreases with increasing Ho3+ concentration resulting in a non-radiative energy transfer from UO2++ to Ho3+. The energy transfer mechanism for the systems is confirmed to be electric dipole-dipole in nature according to Fong-Diestler’s, Forster and Dexter’s and Van Uitert’s theory. The donor-acceptor distances (DD→A) and transfer efficiencies (η), as well as energy transfer probabilities (Pda) in presence of different acceptor concentration, have been calculated.
