Пористый анодный оксид алюминия с его хорошо известной ячеистой структурой был выбран в качестве матрицы для золь-гель-синтеза BaTiO3:Er,Yb. Пористый анодный оксид алюминия изготавливали на кремниевой пластине и алюминиевой фольге. Раствор, соответствующий составу ксерогеля Ba0,76Er0,04Yb0,20TiO3, осаждался на пористый анодный оксид алюминия методом центрифугирования с последующей сушкой и термообработкой при относительно низкой температуре 450 °C на алюминиевой фольге или при 800 °C на кремнии. Пористый анодный оксид алюминия, известный также как оптически анизотропная структура, в эксперименте отличался размером пор и толщиной. По результатам испытаний установлено, что все изготовленные образцы демонстрируют ап-конверсионную люминесценцию эрбия при комнатной температуре при возбуждении диодным модулем в непрерывном режиме сфокусированным излучением лазерного диода на длине волны 980 нм мощностью 200 мВт. Ап-конверсионная люминесценция эрбия характеризуется полосами с максимумом на длинах волн 410, 523, 546 и 658 нм и соответствующими им переходами 2H9/2 → 4I15/2, 2H11/2 → 4I15/2, 4S3/2 → 4I15/2 и 4F9/2 → 4I15/2.</p></abstract><trans-abstract xml:lang="en"><p>In this work, sol-gel synthesis and luminescence properties of erbium and ytterbium doped BaTiO3 (BaTiO3:Er,Yb) in porous anodic alumina are reported. Porous anodic alumina with its well-known tailor-made honeycomb structure was chosen as a template for the sol-gel synthesis of BaTiO3:Er,Yb. Porous anodic alumina was fabricated either on silicon wafer or aluminum foil. The sol corresponding to xerogel content of Ba0,76Er0,04Yb0,20TiO3 was deposited on porous anodic alumina by spinning, which was followed by drying and heat treatment at a relatively low temperature 450 °C on aluminum foil or 800 °C on silicon. Porous anodic alumina known also as an optically anisotropic structure differed in the experiments by diameter of the pores and thickness. Evidently, all fabricated samples demonstrated a roomtemperature erbium upconversion luminescence under excitation in the continuous-wave (CW) mode with a focused 980 nm laser beam of a 200 mW diode module. Erbium upconversion luminescence is characterized by the bands at 410, 523, 546, and 658 nm, corresponding to the 2H9/2 → 4I15/2, 2H11/2 → 4I15/2, 4S3/2 → 4I15/2 and 4F9/2 → 4I15/2.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эрбий</kwd><kwd>иттербий</kwd><kwd>ап-конверсия</kwd><kwd>люминесценция</kwd><kwd>золь-гель-метод</kwd><kwd>многослойные структуры</kwd><kwd>пористый анодный оксид алюминия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>erbium</kwd><kwd>ytterbium</kwd><kwd>upconversion</kwd><kwd>luminescence</kwd><kwd>sol-gel method</kwd><kwd>multilayer structures</kwd><kwd>porous anodic alumina</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке проекта ГКНТ-Молдова Ф22МЛДГ-002; ГПНИ «Фотоника и электроника для инноваций», задание 1.9; ГПНИ «Материаловедение, новые материалы и технологии», задание 2.02, и Национального агентства исследований и разработок Молдовы (проект #22.80013.5007.4BL «Нано- и гетероструктуры на основе оксида цинка и соединений А3В5 для оптоэлектроники, фотоники и биосенсорики»).</funding-statement><funding-statement xml:lang="en">The work was supported financially by the SCNT-Moldova project F22MLDG-002; SPNI “Photonics and electronics for innovation”, task 1.9; SPNI “Materials Science, New Materials and Technologies”, task 2.02, and by National agency for research and development of Moldova under the grant #22.80013.5007.4BL “Nanoand heterostructures based on zinc oxide and А3В5 compounds for optoelectronics, photonics and biosensorics”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Goldschmidt J.
