В работе измерены спектральные зависимости оптической плотности аморфных тонких пленок оксидной натрий-вольфрамовой бронзы тетрагональной структуры состава NaWO, конденсированной на стеклянные подложки, термостатированные при температурах 373,473 и 573 K, а так же отожженные на воздухе и в вакууме, и электрохромно окрашенных. В качестве исследуемой оптической характеристики была выбрана оптическая плотность D, пропорциональная, как известно, коэффициенту поглощения. Спектральные измерения пленок, осажденных на подложки в диапазоне температур 373,473 и 573 K показали однотипность спектральных характеристик, с пиком экситонного поглощения в ближнем ультрафиолете. Полоса минимального поглощения лежит в диапазоне длин волн 400÷460 нм, а примесного поглощения - широкой полосой в области 650 ÷1000 нм с максимумом в диапазоне 900÷1000 нм. Подобная спектральная характеристика и определяет сине-голубой цвет тонкой пленки на просвет. Изучение оптических свойств тонких пленок натрий-вольфрамовых бронз представляет собой актуальную задачу. The spectral dependences were measured of the optical density of amorphous thin films of sodium-tungsten oxide bronze of the tetragonal structure and the composition NaWO, condensed on glass substrates, thermostated at temperatures of 373, 473 and 573 K, as well as annealed in air vacuum, and electrochromically colored. The optical density D, which is proportional, as is known, to the absorption coefficient, was chosen as the studied optical characteristic. Spectral measurements of films deposited on substrates in the temperature range of 373, 473 and 573 K showed the same type of spectral characteristics, with a peak of the exciton absorption in the near ultraviolet. The band of minimum absorption lies in the wavelength range of 400÷460 nm, while that of the impurity absorption is a wide band in the region of 650÷1000 nm with a maximum in the range of 900÷1000 nm. This spectral characteristic determines the blue-blue color of a thin film in transmission. The study of the optical properties of thin films of sodium-tungsten bronzes is an urgent problem.
