Laser-Heating Characteristics of CuO-Incorporating Glasses

Abstract

Laser sealing with glass frits appears a promising technology for sealing various electronic devices (e.g., solar cells, displays) due to its several advantages. The purpose of this study is to understand the relationship between the composition of glasses and their laser-heating conditions. To allow glass to be sealed using laser heating, CuO was added to two different glass systems, in different amounts. The optical absorptivity of the glass samples was related directly to their CuO content. The laser-heating temperature and the CuO content exhibited a proportional relationship. Furthermore, the heating temperature increased linearly with the laser power used. From these results, we could determine the appropriate laser-heating conditions and CuO content for sealing electronic devices using laser-sealing technology.

Biodegradation-tunable mesoporous silica nanorods for controlled drug delivery

“…7 fabricated with higher water content is ascribed to fine nanopores formed between delicate SiO 2 frames consisting of small polymer chains which are rapidly created by a quick gel reaction [25][26][27].…”

“…4). In the previous studies by Lee et al [26], porous silica was obtained using precursor solutions with the water content range of H 2 O/TEOS =7.8~18 and HCl catalyst. This conforms well to our results in this experiment.…”
