Se sintetizaron películas compuestas de alcohol polivinílico/yoduro de plomo (PVA/PbI2) con diferentes concentraciones de PbI2 utilizando un proceso de evaporación de solventes a baja temperatura y de bajo costo. Las propiedades estructurales de las partículas obtenidas fueron analizadas mediante difracción de rayos X (DRX) y microscopía electrónica de barrido (MEB). Los resultados de DRX mostraron una naturaleza predominantemente cristalina, exhibiendo los planos de reflexión característicos del politipo 2H del yoduro de plomo. Las micrografías MEB mostraron una morfología hexagonal con un tamaño promedio de partícula de 13.2 µm. Los parámetros ópticos de las películas compuestas se midieron mediante espectroscopía UV-Vis, encontrándose que la brecha de energía indirecta para el PVA puro es de 4.65 eV. En contraste, las películas de PVA/PbI2 con concentraciones de 0.5, 1.0, 1.5 y 2.0 % en peso de PbI2 mostró una transición directa de 5.16 eV y una transición indirecta de 4.45 eV. La resistencia eléctrica de la película de PVA se midió en 4.32 × 107 Ω. Los análisis químicos mediante espectroscopía infrarroja por transformada de Fourier (FTIR) indicaron que la adición de partículas de PbI2 no modifica las bandas características del PVA, lo que sugiere la ausencia de enlaces químicos entre las partículas y la matriz polimérica. Las propiedades ópticas y eléctricas obtenidas sugieren que las películas compuestas de PVA/PbI2 tienen potencial para aplicaciones en el campo de la optoelectrónica.
