Notes:
An infrared absorption spectrometer for use with high-temperature liquids is described. The system has been used for liquid semiconductors at temperatures up to 550 °C having absorption edges as low as 0.3 eV. The optical cell consists of a thin (100–600 μm) gasket of graphite foil sandwiched between two optical flat windows and equipped with a fluid reservoir and heating block. This design allows the use of any optical windows chemically compatible with the sample. We have used several infrared windows to measure the optical absorption edge in selenium, selenium–tellurium, and selenium–thallium alloys down to 0.2 eV. This represents an improvement in the previous range of measurement which has been limited by the 0.5-eV cutoff of fused quartz cells.
