| Abstract: | A study of energy transfer from samarium to erbium ions in zinc phosphate glass has been performed for a range of donor (1.0
wt% fixed) and acceptor concentrations ranging from 0.2 wt% to 1.2 wt%. The intensity of emission spectra of Sm3+ ions in the presence of Er3+ ions shows an overall decrease, thereby suggesting a non radiative energy transfer from Sm3+ ions to Er3+ ions. The interaction mechanism between the donor and acceptor ions is found to be mainly electric dipole-dipole in nature.
The parameters required for the quantitative study of energy transfer e.g. energy transfer efficiencies, transfer probabilities,
critical transfer distances have been computed. |
