Researchers from Iran University of Science and Technology in association with researchers from University of La Laguna, Spain, succeeded in the production of glass ceramic nanocomposite with the ability to convert infrared waves into visible ones.
Transparent glass ceramic nanocomposites were the main subject of the research, and it was tried to determine effective parameters in selecting the composition and process mechanism in them. Dr. Mohammad Hossein Imaniyyeh, one of the researchers, stated, "After carrying out studies, we precisely and systematically investigated glass ceramics in SiO2-Al2O3-MF (M=Ca or La) system with a new and technical approach. It must be pointed out that the majority of the researches in this field had been carried out by focusing on physics and optics. Moreover, contradictory reports have been presented on the power and efficiency of various systems."
The researchers carried out the research in three phases to achieve their objectives. Dr. Imaniyeh explained the phases. "In the first phase, we aimed to produce glass ceramics that are able to convert infrared to visible light. The purpose in the second phase was to determine effective parameters in the conversion of infrared waves into visible ones. The parameters were categorized and their effects were individually inspected. Finally, we determined the role of the parameters in optical behavior and materials science of the glass ceramics. Increase in the efficiency was another objective of the third phase."
Dr. Imaniyeh believes that the results of the research can be used in devising technical knowledge in the production of glass ceramic filters used in solar cells, electronics and aerospace industries.
Results of the research have been published in Journal of the American Ceramic Society, vol. 97, issue 3, March 2014, pp. 782-788.
