Commercial silicate microscope slides of the following system were used: SiO2-Na2O-K2O-CaO-MgO-Al2O3 with Fe2O3-SO3 impurities. Molecular clusters were obtained by low-temperature ion exchange in a melt of 0.1 % AgNO3/99.9 % NaNO3 mol.% for 10 and 15 min at 320°C. The luminescent properties of silver molecular clusters in the ion-exchange layer of microscope slides were studied. Bands of silver clusters of different sizes (Ag1-5) were found in the luminescence spectra. In this case, clusters Ag1-3 are excited by shorter wavelengths, and clusters Ag4-5 only by far ultraviolet and visible radiation up to 500 nm. In the process of ion exchange lasting up to 10 minutes, the appearance of luminescence selectivity was revealed, which occurs due to the presence of a low concentration of silver clusters of different sizes Ag1-5 in the ion-exchange layer. The obtained results can be used in the development of a photosensitive element for a selective ultraviolet radiation detector.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>серебряные молекулярные кластеры</kwd><kwd>ионный обмен</kwd><kwd>силикатное стекло</kwd><kwd>люминесценция</kwd><kwd>селективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silver clusters</kwd><kwd>ion exchange</kwd><kwd>silicate glass</kwd><kwd>luminescence</kwd><kwd>selectivity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (грант № 20-19-00559).</funding-statement><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation (Project No. 20-19-00559).</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">Gy R.
