Optical Properties of Nanoporous Al2O3 Matrices with Ammonium Dihydrogen Phosphate Crystals in Nanopores

Abstract

In this paper, the technology of growing ammonium dihydrogen phosphate (ADP) crystals in pores of nanoporous aluminum oxide (Al2O3) matrices was presented. On the grown nanocomposites, the optical properties of such structures were studied. In particular, the direct and diffuse optical transmission, as well as specular reflection of Al2O3 matrices with ADP crystals grown in nanopores, were analyzed. From the performed experimental studies, it can be concluded that the transmission and scattering of pure Al2O3 porous matrices and with ADP crystals in nanopores depends largely on the properties of the Al2O3 matrices and the technology of their production.
