| Abstract: | A study of
non-radiative energy transfer in Eu3+-Er3+ has been done
by observing the steady state emission of Eu3+ with varying
concentration of Er3+ in zinc phosphate glass at room temperature.
It has been observed that Eu3+ ion emission intensity decreases with
increasing Er3+ concentration resulting in a non-radiative energy
transfer from Eu3+ to Er3+. The energy transfer mechanism
for Eu-Er system is mainly found electric dipole-dipole in nature. Various
parameters necessary for quantitative study e.g. energy transfer efficiencies,
transfer probabilities etc. between Eu3+ and Er3+ have
been computed. |
