title: [Analysis of chromaticity and spectral properties of car solar films].
abstract: Chromaticity and spectral properties of the ordinary car solar films of a certain brand in the market were qualitatively measured and analyzed with WGS-9 chromaticity analysis system, UV-Vis 8500 double-beam ultraviolet/visible spectrometer and WGD-4A grating spectrometer. The result shows that getting low infrared/ultraviolet transmissivity and high visible light transmissivity at the same time is impossible, so only one aspect can be fulfilled when we choose solar films. Solar films with main wavelength 587.3 nm (Cambridge blue) and 522.1 nm (diamond green) should be chosen if we want to get high visible light transmissivity and low ultraviolet transmissivity. Solar films with main wavelength 497.3 nm (diamond blue) and 507 nm (emerald green) should be chosen if the authors want to get high visible light transmissivity and heat insulation function.
