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 (D_D→A) and transfer efficiencies (η), as well as energy transfer probabilities (P_da) in presence of different acceptor concentration, have been calculated.

磷酸锌玻璃中UO2 ++与Ho3 +的光学相互作用的研究

通过观察室温下磷酸锌玻璃中不同浓度的Ho ³⁺引起的UO ₂ ⁺⁺的稳态发射，研究了磷酸锌玻璃中UO ₂ -Ho系统的非辐射能传递。已经观察到，随着Ho ³⁺浓度的增加，UO ₂ ^++的离子发射强度降低，导致从UO ₂ ⁺⁺到Ho ³⁺的非辐射能量转移。根据Fong-Diestler，Forster和Dexter和Van Uitert的理论，该系统的能量传递机制实际上是电偶极-偶极子。供体-受体距离（D _D→A）和转移效率（η）以及在不同受体浓度下的能量转移概率（P _da）已被计算。
