| Abstract: | Non-radiative energy transfer from Eu3+
to Tm3+ has been studied by observing the steady state
emission of Eu3+ with varying concentration of Tm3+ in
zinc phosphate glass. It has been observed that Eu3+ ion emission
intensity decreases with increasing Tm3+ concentration resulting in
a non-radiative energy transfer from Eu3+ to Tm3+ whereas
energy transfer from Tm3+ to Eu3+ was not observed
between donor and acceptor ions. This energy transfer has been explained on the
basis of cross-relaxation of energy. The energy transfer mechanism and other
parameters related to energy transfer between Eu3+ and Tm3+ have
been computed. |
