Summary, etc. <strong>Dy<sup>3+</sup>, Sm<sup>3+</sup> ions doped PEO+PVP polymer films and also a host PEO+PVP polymer films have successfully been synthesized by solution casting method. For the PEO+PVP film, its XRD, FTIR, Raman and TG-DTA profiles have been investigated in order to understand its structural and thermal properties. Dy<sup>3+</sup> doped film has displayed a <em>blue</em> emission under an UV source. Photoluminescence spectra have been measured to study its optical properties. For observed <em>blue</em> emission at 480 nm (<sup>4</sup>F<sub>9/2</sub>→ <sup>6</sup>H<sub>15/2</sub>) of Dy<sup>3+</sup> film, its decay curve has been measured in evaluating the lifetime of the blue emission. The Sm<sup>3+</sup> polymer film has displayed an<em> orange</em> emission under an UV source. For this Sm<sup>3+</sup> film, emission spectra have been measured to evaluate its optical properties. For the orange emission at 600 nm (<sup>4</sup>G<sub>5/2</sub>→ <sup>6</sup>H<sub>7/2</sub>) of Sm<sup>3+</sup>,<sup> </sup>the transitions of Sm<sup>3+</sup> are clearly explained in the form of an energy level diagram. In the co-doped system, an energy transfer between the dopant ions in the host polymer matrix has been explained. These results suggest these films as <em>blue</em> and <em>orange</em> luminescent optical materials.</strong>
