Notes:
Sm2O3 optical thin films were prepared by hydrothermal method using samarium dichloride assource material. The influence of preparation temperature on the crystallinity, morphology and opticalproperties of Sm2O3 thin film were investigated. The as-fabricated thin films were characterized by X-raydiffraction, atomic force microscopy and spectrophotometer. Results show that the prepared thin film isSm2O3 crystallites thin film with compact and uniform surface microstructures. Transmittance curvedisplays that the Sm2O3 crystallites thin films are transparent to visible and infrared light; and possessexcellent absorbency of UV light. With the increase of deposition temperature, the crystallinity andoptical properties of the prepared Sm2O3 thin film are improved. With the increase of hydrothermaltemperature from 170 °C to 185 °C, the bandgap of the thin film increase from 2.88 eV to 2.95 eV
