摘要：

An influence of nanocrystalline sizes of YAB:Cr particles incorporated within olygoetheracrylate polymer matrix on the two-photon absorption was investigated. Maximal values of the two-photon absorption diagonal tensor component was observed at low temperatures (about 4.2 K) and corresponded to concentration of the YAB: Cr NC about the 3% by weight and about 22 nm in sizes. The Cr3+ ions inside investigated NC play the crucial role in the observed nonlinear optical phenomena. The observed temperature dependence is explained within a model of anharmonic electron-phonon contribution in the nanocrystallites.
