Abstract: A study of non-radiative energy transfer in Eu<sup>3+</sup>-Er<sup>3+ </sup>has been done by observing the steady state emission of Eu<sup>3+</sup> with varying concentration of Er<sup>3+ </sup>in zinc phosphate glass at room temperature. It has been observed that Eu<sup>3+ </sup>ion emission intensity decreases with increasing Er<sup>3+</sup> concentration resulting in a non-radiative energy transfer from Eu<sup>3+</sup> to Er<sup>3+</sup>. 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 Eu<sup>3+</sup> and Er<sup>3+ </sup>have been computed.
