“…The main disadvantage of such registration media is a relatively low photosensitivity about ~ 10-10 2 сm 2 /J [1]. In [2,3] the authors have tried to rise photosensitivity of the metal-ChG structures by applying of corona charge to ChG thin layers during their light exposure. It was established [3], that application of negative corona discharge during recording of optical holographic diffraction gratings in Cu-As 2 Se 3 thin film structures , in comparison of positive corona discharge, increases the holographic sensibility, the diffraction efficiency and the depth of the chemical etched relief.…”

The object of our current investigation is Cu-As2Se3 thin film structures. The impact of corona discharge on photoinduced modifications of the transmission spectra of both asdeposited and exposured with actinic light of the Cu-As2Se3 structures have been studied. Two cases have been investigated. First normal irradiation of the film structures without charging, and another one, when exposure was switched on, 7 kV corona charge at different polarity was applied. As a result, in the region of the weak absorption in the transmission spectra the photobleaching effect was observed and in the region of the strong absorption the photodarkening phenomena was manifested. In the region o weak absorption higher values of photobleaching was observed during exposure in the field of positive corona discharge. The obtained results are qualitatively analyzed taking into account the photodarkening of the semiconductor during it doping with Cu ions as well as transmission increases of the structure during photodiffusion of the cupper in the amorphous semiconductor.

We propose the fabrication of surface relief holograms via selective SiO2 deposition on soda-lime silicate glass substrates. Initially, the original hologram was recorded on an azobenzene photosensitive polymer film coated on the soda-lime silicate glass by irradiation with a conventional continuous wave Ar+ laser with a wavelength of 514.5 nm. The hologram was transferred to the soda-lime silicate glass surface via a corona discharge treatment as an index modulation hologram, which was created by partial substitution of protons for sodium ions during the corona discharge treatment in air. After the corona discharge treatment, the polymer film was removed from the substrate. The diffraction efficiency of the index hologram on the soda-lime silicate glass was estimated to be 5.8 × 10−2% at a wavelength of 532 nm. Finally, the glass substrate was subjected to corona discharge treatment in air with vaporized cyclic siloxane. A surface relief hologram with the diffraction efficiency of 2.3% was successfully fabricated on the soda-lime silicate glass.

Thin-film Cu–As_2S_3 and Ag–As_2S_3 structures obtained by successively evaporating Cu(Ag) and As_2S_3 in vacuum on glass substrates have been studied. Samples of these structures have been kept in air at room temperature in the dark for 6 months, and transmission spectra have been periodically taken of these samples. The logarithm of inverse transmission coefficient in the transparency domain of As_2S_3 has been used as a measure that is proportional to the thickness of the metal film. It has been found that for Ag–As_2S_3 the thickness of the metal film varies with storage time linearly, whereas for Cu–As_2S_3 this dependence can be described by two different linear sections. From the decrease in metal film thickness, it has been concluded that the Ag–As_2S_3 structure is more stable than Cu–As_2S_3. It has been supposed that silver, unlike copper, does not react with As_2S_3 when the structures are stored in the dark, although it permanently diffuses into As_2S_3 during storage.
