Emissivity of tin
WebABSTRACT. TiN x films were deposited using direct current reactive magnetron sputtering on glass substrates, and the variation of resistivity and infrared emissivity of TiN x films deposited at different substrate temperatures was investigated. The N/Ti ratios of prepared films were off-stoichiometric, and reached the highest value 0.97 at 350°C. The results … WebSep 1, 2011 · The emissivity changes with the temperature in heat treatment between room temperature and 350 °C are resulted from relative vibration between different ions in ITO films and the improvement of crystallinity. While, noticeably, the emissivities of all films are below 0.3 in the whole heat treatment process.
