| Abstract: | Steady state
emission of terbium (Tb3+) with varying concentration of holmium (Ho3+)
in zinc phosphate glass has been studied. Decrease in emission intensity of Tb3+
with increasing Ho3+ concentration indicates a non-radiative
energy transfer from Tb3+ to Ho3+. The energy transfer
mechanism, energy levels of Tb3+ and Ho3+ involved
in energy transfer and other parameters necessary for the quantitative study
e.g. energy transfer efficiencies, transfer probabilities, critical transfer
distance etc. have been computed. |
