Abstract

Films of samarium (Sm3+)-doped polyvinyl alcohol (PVA) have been synthesized via chemical method, starting from samarium nitrate (SmCl3.6H2O) solutions as a source of Sm3+ ions. Photoluminescence (PL) and UV-visible spectroscopy were used to investigate the spectroscopic activity of Sm3+ ions doping in PVA. Prominent emission bands of Sm3+-doped PVA have been observed for the transitions 4G5/2→6H5/2, 4G5/2→6H7/2 and 4G5/2→6H9/2 at 532, 582 and 654nm, respectively, using 400nm radiation source for excitation.
