OPTICAL AND MAGNETO-OPTICAL PROPERTIES OF Nd3S4 SINGLE CRYSTALS

wavelength for WSe2 single crystal The interpretation of experimental results, in terms of the direct and indirect transitions is most often performed with the help of the following

The luminescence is practically absent in the interband (including X-rays) excitation crystals CdBr 2 : Ag+, but manifested in the excitation light from the region 3.68 eV.. In

The structure of the absorption band in the visible and near infrared regions of the spectrum for polyvalent metals is determined on the basis of the interband transitions, which are

INTRODUCTION Magneto-optical transitions in quantum wells have been actively studied in recent years.' The hole wave functions and the transition matrix elements are usually

The RT PL spectra of both undoped and europium doped fibers are shown in Fig. Under UV excitation, the undoped transparent fiber exhibits an unstructured broad emission band peaked
