Synthesis, structural, and optical behavior of erbium-doped silicophosphate glasses for photonics applications.

Erbium-incorporated silicophosphate glasses are very desirable in principal sectors such as photonics, optoelectronics, lasers, and illuminating diodes. The focus of the current investigation has been on determining how the erbium dopant affects the optical, physical, and structural characteristics of the silicophosphate-based glasses. The pure silicophosphate glasses and doped with various contents of erbium were prepared by the sol-gel process in this work.

Alloy Disordering Effects on the Thermal Conductivity and Energy Gap Temperature Dependence of CdZnSe Ternary Crystals Grown by the Bridgman Method.

Investigated in this work, CdZnSe-mixed ternary compounds were grown by the Bridgman method. Several compounds with zinc content varying in the range 0 < x < 1 were produced between two binary parents, CdSe and ZnSe crystals. Using the SEM/EDS technique, the accurate composition of formed crystals was determined along the growth axis.

Generation of red light with intense photoluminescence assisted by Forster resonance energy transfer from Znq and DCM thin films.

In this work, a novel experimental investigation of photoluminescence properties of Znq thin films co-doped with different concentrations of DCM were performed. The thin films were successfully deposited on glass substrates with different compositions, under high vacuum, by using the vacuum evaporation technique. For all compositions, the photoluminescence was measured at room temperature and also at low temperature in a wide range from 77 to 300 K with a step of 25 K in a high vacuum.

Optical and morphological properties of Curcuma longa dye for dye-sensitized solar cells.

New experimental results of morphological and optical properties of Curcuma longa dye thin film were investigated. The thin films were deposited by physical vapor deposition technique. Morphological properties were measured using atomic force microscopy technique and they show a granular structure which above there are nanotubes shapes.

Optimization of hyperconnected mobile modular production toward environmental and economic sustainability.

Logistics sustainability is increasingly becoming a central focus of businesses, when most societies are aware of the influence of industry on both the environment and human health. To address the drawbacks of the way logistics systems have been designed, a new logistics system called Physical Internet has been proposed. This system relies on the creation of hyperconnected logistics systems.
