Только 20 % этого увеличения вызвано преобладанием двух- и одноэлектронно восстановленных ГПА при малых и больших концентрациях соответственно. Установлено, что основная причина концентрационного эффекта связана с уменьшением размеров наночастиц ФВК при уменьшении ее концентрации в пленках.</p></abstract><trans-abstract xml:lang="en"><p>As a result of a detailed analysis of the previously discovered effect of the concentration of phosphotungstic acid (PTA) on its reduction in nanocomposite films with poly(vinyl alcohol) (PVA) under the influence of gamma radiation, it was established that the molar absorption coefficient at the maximum of PTA band caused by intervalence charge transfer in the reduced PTA heteropolyanions (HPA), at low PTA concentrations is 8 times higher than at high concentrations. Only 20% of this increase is due to the predominance of two- and one-electron-reduced HPAs at low and high concentrations, respectively. It is concluded that the main reason for the concentration effect is associated with a decrease in the size of PTA nanoparticles with decreasing PTA concentration in the films.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нанокомпозит</kwd><kwd>поливиниловый спирт</kwd><kwd>фосфорно-вольфрамовая кислота</kwd><kwd>радиационно-индуцированное восстановление</kwd><kwd>межвалентный перенос заряда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanocomposite</kwd><kwd>poly(vinyl alcohol)</kwd><kwd>phosphotungstic acid</kwd><kwd>radiation-induced reduction</kwd><kwd>intervalence charge transfer</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке Белорусского республиканского фонда фундаментальных исследований (грант № Ф23МЭ-033).</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">M.
