“…Spectrophotometric and X-ray diffraction studies proved the presence of the nanocrystals of desired composition in this dielectric matrix. The rather typical position of the absorption band of the Z 1,2 exciton of CuCl, which is indicated in the room-temperature absorption spectra of the glasses, is in agreement with data in the literature on inorganic glasses containing CuCl nanocrystals [5][6][7][8][9]. The twoband structure of the absorption spectrum clearly suggests the presence of spin-orbit splitting, which is characteristic of semiconductor nanocrystals and copper (I) chloride, in particular [9].…”

The absorption spectra of glasses of fluorine-phosphate matrix in the near-UV spectral region have been investigated in the temperature range from 20 to 420°C. It is shown that the absorption bands in this spectral region are exciton absorption bands of copper chloride(I) nanocrystals. Results of X-ray diffraction analysis of the glasses are presented. It is shown that the temperature dependences of the exciton absorption bands of CuCl nanocrystals, obtained upon heating and cooling samples, have a a form of hysteresis.

“…CuCl nanocrystals exhibited strong exciton absorption in the near-UV spectral region. Glasses containing CuCl nanocrystals are characterized by high nonlinear optical response and photochromism [5,6]. Currently, it is known that the nanocrystalline copper halide phase segregates in glasses of borate [3,6,7] and silicate [5,8] matrices.…”

“…It is well known, that the CuCl nanocrystals have only the exciton luminescence band in the UV spectral range, which can be observed at cryogenic temperatures [9][10][11] . The compare with literature data allows us to make a conclusion that the observed in the investigated glass luminescent band is not directly connected with Cu + ions or Cu + -Cu + dimers, although they can make the contribution to the short-wavelength part of this band.…”

The research of the luminescent properties of the inorganic glasses doped with copper molecular clusters that can be used as a sensitive medium of the temperature sensors is presented. The luminescent spectra of the borate and phosphate glasses in the temperature range 77-623 K are examined. The big luminescent thermochromism for borate glasses is observed: from 293K to 623K the luminescent band shift is found out to be 110nm.

This paper presents a comparative analysis of the luminescence and absorption of glasses with molecular clusters of silver and selenium and nanocrystals of copper chloride and cadmium sulfide from the viewpoint of spectral down-conversion of short-wavelength solar radiation into the spectral interval of the maximum efficiency of the photoelectric converter of a solar cell. It is shown that UV and violet radiation can be efficiently converted into the 450-700-nm spectral region by appropriately choosing the luminescence centers in glass, and this promises to reduce the number of stages in a solar cell.
