“…Organic dyes are effective in spectral sensitization of photophysical and photochemical processes in different semiconductors (AgHal, ZnO, TiO 2 and other) both in visible and infrared ranges (Akimov et al 1980;Goryaev 2015;2016;2018;2019;James 1977). Spectral sensitization is the most effective control method of the sensitivity degree and the sensitivity spectrum for classic silver halide photo materials (James 1977).…”

The paper discusses spectral sensitized photo processes in silver bromide caused by dyes adsorbed on the surface of silver stearate via the lightguide mechanism and a direct hit of the luminescent light from dye molecules localized near the microcrystal of silver bromide to the microcrystal of silver bromide. The paper submits an estimation of the contribution of dye molecules localized on the surface of silver stearate to overall spectral sensitization. These calculations demonstrate that the contribution of dye molecules adsorbed on the particle of silver stearate to spectral sensitization of silver stearate-silver bromide structure is comparable to the contribution of dye molecules placed on the microcrystal of silver bromide. Dye molecules localized on the particle of silver stearate allow to raise the efficiency of spectral sensitization by 40 to 60 percent.

“…Silicon CCD matrices are used as image sensors in modern electron photography systems, and light filters used for the color separation system lead to a loss of energy and valuable information [9,10]. The dye sensitization of the photoconductivity in powdered silicon and photovoltaic effect in the monocrystallic silicon were found in works [11,12]. In the present study we consider the photoelectric sensitivity formation processes in semiconductors with dyes applied on the surface and the possibilities to control this processes.…”
