The infrared optical properties and the microstructure of cesium iodide (CSI) thin film have been investigated. In this paper,
the cesium iodide thin film were prepared on CVD (chemical vapour deposition) diamond substrate by molybdenum
boat thermal evaporation in 2×10-3 Pa vacuum pressure, while deposition rate was monitored and demonstrated at 2~3 nm/s
by quartz crystal oscillation controller. The films were observed and analyzed by the Fourier transform infrared spectrometer,
X-ray diffraction analyzer and scanning electron microscopy. CSI film infrared spectra transmittance curve shows that the
cesium iodide transparent area can be up to 80 micron which is the far infrared region. When affected by the moist air, the
spectral curve shows the appearance of the infrared absorption band in the ranges of 2.66~2.85 μm. XRD results indicate the
cesium iodide film is polycrystalline. And the scanning electron microscopy results shows that the average grain size of the
cesium iodide film become larger after the cesium iodide film is placed in the moist air.
