| Summary: | This study investigates the impact of violet laser irradiation on the optical properties of thick films composed of polyvinyl alcohol (PVA), methyl orange (MO), and their composite (PVA/MO). Aimed at exploring potential medical applications, the films were synthesized through a casting process involving the dissolution of PVA and MO in distilled water. The optical properties, including absorbance spectra, energy gaps, and various optical constants, were meticulously measured before and after exposure to laser irradiation. The results revealed a notable decrease in the absorbance spectra and optical constants, along with an increase in the energy gaps, suggesting a structural modification induced by the laser treatment. These findings hold significance for the advancement of materials with customized optical features, potentially serving as a model for future developments in optoelectronic and photovoltaic devices. The research outcomes provide a foundation for the exploration of polymers and dyes in medical applications, particularly in the realms of non-invasive surgical procedures and simulations. |
