Abstract:
Abstract Heat treatment conditions effect on the characteristics of exciton absorption and luminescence of CuCl and CuBr nanocrystals in potassium-aluminaborate glass is studied. The size effect of the band edge absorption and luminescence energy is confirmed. The simultaneous presence of copper halide nanocrystals and free monovalent copper ions in the glass matrix is shown. Possible conditions for the formation of mixed CuCl-CuBr crystals are considered.

Abstract:
When CuBr nanocrystals (NCs) embedded in poly methyl methacrylate are strongly excited, there appears a new luminescence band at the low energy side of exciton luminescence peak. The luminescence band is associated with biexcitons in the CuBr NCs. As the excitation intensity increases, the biexciton luminescence band shows obvious broadening, while the exciton band does not. Interaction among more than three excitons may cause this broadening effect. Optical gain has also been found by pump-probe measurement around the biexciton luminescence band at 77K. The decay time of the optical gain 15ps

Abstract:
The paper describes the research of temperature effect of potassium-alumina-borate (PAB) glass with CuBr nanocrystals, which was obtained in optical wavelength region for the first time. Temperature dependence of optical density at different wavelengths was examined. Melting and crystallization temperatures were evaluated for different nanocrystals sizes. Great changes of exciton absorption band influenced by temperatures below 100°C were recorded. Propositions for studied glass application as tunable filters in electro-optic circuit were suggested.

Abstract:
Persistent hole-burning phenomena in ion-doped glass and organic-molecule-doped organic glass have been well known. In recent years semiconductor nanocrystals have been studied extensively because of their novel optical properties such as large optical nonlinearities, and their possibility for applications, such as lasers, ultrafast optical devices, and so on. However, so far "persistent spectral hole-burning (PSHB)" phenomenon in semiconductor nanocrystals has never been reported until the PSHB phenomenon was observed in CdSe and CuCl nanocrystals in our laboratory. Therefore, we may be able

Abstract:
Because large third-order refractive nonlinearities, γ, are expected, much study on nanocrystal doped glasses has focused on the nonlinear optical properties at or near the single photon resonance.1 Although γ is smaller in the single-photon transparent region, its temporal response is expected to be pulse-width limited. More importantly, since the potential use of these materials as optical devices depends on the figure-of-merit ratio proportional to γ/(ατ or (βτ), where α and β are the linear and nonlinear absorption coefficients, respectively, and τ is the response time, a possibly larger f
