Abstract

A couple of Poly vinyl alcohol (PVA) films with Sm³⁺ and Dy ³⁺ ions have been prepared by a conventional solution cast technique. For these Sm³⁺ and Dy³⁺ doped PVA films, Fourier transform infrared and also absorption spectral measurements have been carried out. Excitation and emission spectra and decay curves have been recorded to understand emission performanceof the polymers namely Sm³⁺: PVA film with λ_exci = 400 nm and Dy³⁺: PVA film with λ_exci = 349 nm. Emission performances of these films have been explained in terms of relevant energy level schemes.
