Золь приготовлен на основе ацетата стронция, тетраизопропоксида титана, уксусной кислоты и монометилового эфира этиленгликоля. Пленки титаната стронция формировались последовательным нанесением пяти слоев с промежуточной сушкой каждого слоя и окончательной термообработкой в диапазоне температур 500-750 °С. Из анализа спектров пропускания установлено, что полученные пленки характеризуются шириной запрещенной зоны, уменьшающейся от 4.46 до 3.84 эВ при переходе от рентгеноаморфных пленок к кристаллическим с показателем преломления 1.996 (l= 620нм), обусловленным высокой плотностью упаковки 81.5 % от плотности монокристаллического титаната стронция. </p></abstract><trans-abstract xml:lang="en"><p>The transmission spectra of sol-gel derived strontium titanate films on quartz substrates have been studied in the optical range from 200 to 1100 nm. The sol is prepared on the basis of strontium acetate, titanium tetraisopropoxide, acetic acid, and ethylene glycol monomethyl ether. Strontium titanate films have been fabricated by successive deposition of five layers with intermediate drying of each layer and the final heat treatment in the temperature range from 500 to 750oC. It is concluded from the analysis of the transmission spectra that the prepared films are characterized by the band gap value decreasing from 4.46 to 3.38 eV at the transformation from amorphous to crystalline films with a refractive index reaching 1.996 (at 620 nm) and high-density packaging up to 81.5% of that for monocrystalline strontium titanate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>золь-гель метод</kwd><kwd>титанат стронция</kwd><kwd>оптические спектры пропускания</kwd><kwd>показатель преломления</kwd><kwd>ширина запрещенной зоны</kwd><kwd>sol-gel method</kwd><kwd>strontium titanate</kwd><kwd>optical transmission spectra</kwd><kwd>refractive index</kwd><kwd>band gap energy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">F.
