SPECTRA OF ZnO SUPERDISPERSED PARTICLES POLARIZED IN AN MAGNETIC FIELD
This paper discusses the spectra of photo - and ion-luminescence (PL and IL) of ultrafine crystals (UDC) ZnO deposited on the substrate in an magnetic field. UDC ZnO was obtained by separation in a water emulsion industrial phosphor (K-56). The fluorescence spectra for initial sample have a relativ...

| description | This paper discusses the spectra of photo - and ion-luminescence (PL and IL) of ultrafine crystals (UDC) ZnO deposited on the substrate in an magnetic field. UDC ZnO was obtained by separation in a water emulsion industrial phosphor (K-56). The fluorescence spectra for initial sample have a relatively intense broad band in the visible region, which during the deposition of the initial sample in magnetic field becomes less intense. PL spectra for ZnO UDC have weak intensity bands in the visible region. And UDC PL spectra for ZnO deposited in an magnetic field, and do not have this band. While this exciton band with λмах=401nm for all the samples remains almost unchanged. When exposed to samples of oxygen ions spectra were obtained ionoluminescence, which differ from the fluorescence spectra. The analysis of the spectral characteristics obtained under the influence of ions sour-kind of the ZnO crystals shows that the intensity of the broad band in the visible region responsible for the defects formed by oxygen ions. |
