OPTICAL AND STRUCTURE CHARACTERISTICS OF VACUUM-DEPOSITED LAYERS

We report results of a complex study of growth rates, refractive index es, and structure of real cryocrystals of nitrous oxide as well as lig ht and heavy water. The corresponding experimental setup and the relev ant experimental procedures are described. We demonstrate possibilitie s of the available experiment-and-computing complex for the purposes o f studying growth kinetics, thermal properties, and structure-morpholo gic characteristics of real cryocrystal quench-condensed deposits. A s tructure transformation from the low-temperature highly amorphized sta te to the Pa3 structure has been observed at a temperature near 40 K i n nitrogen monoxide. The spectrum of spontaneous luminescence bursts o f freshly prepared N2O samples has been measured. It consists of two m ain bands in the red and blue domains of the visible spectral range. E xistence of three structural modifications of vacuum condensed water d eposits has been confirmed and their temperature boundaries of existen ce revised. Our results on heavy water cryocondensates allowed us to i nfer ultrapolymorphism in this solid.
