MoO3 is extensively studied in the mid infrared range due to the strong anisotropy of its optical properties. We investigate the mid-infrared thermo-optical properties of polycrystalline alpha-phase Molybdenum trioxide (a-MoO3) thin films grown onto SiO2 substrates in the temperature range 20°C-250°C reporting a thermo-optic coefficient of the mean order of 10-4 K-1.

Abstract
MoO3 is extensively studied in the mid infrared range due to the strong anisotropy of its optical properties. We investigate the mid-infrared thermo-optical properties of polycrystalline alpha-phase Molybdenum trioxide (a-MoO3) thin films grown onto SiO2 substrates in the temperature range 20°C-250°C reporting a thermo-optic coefficient of the mean order of 10-4 K-1.
