Abstract:

The photoluminescence properties of a composite material prepared by the introduction of the nanosized phosphor Zn2SiO4:Mn2+ into porous anodic alumina have been investigated. Scanning electron microscopy studies have revealed that Zn2SiO4:Mn2+ particles are uniformly distributed in 70\% of the volume of the pore channels. The samples exhibit an intense luminescence in the range of 2.3-3.0 eV, which corresponds to the emission of different types of F centers in alumina. After the formation of Zn2SiO4:Mn2+ nanoparticles in the pores, an intense photoluminescence band is observed at 2.4 eV due to the (4) T (1)-(6) A (1) electronic transition within the 3d shell of the Mn2+ activator ion. It has been found that the maximum of the photoluminescence of Zn2SiO4:Mn2+ xerogel nanoparticles located in the porous matrix is shifted to higher energies, and the luminescence decay time decreases significantly.
