Degradation phenomena and photo luminescence for silica glass irradiated with 266 nm-laser

ABSTRACTPhoto-luminescence(PL) in VAD silica preforms sintered under reducing or oxidizing condition was observed. Two types of diamagnetic luminescence centers and the Si-E′ center were found in pure silica glass. The intensity of photoluminescence was strongly dependent on the sintering atmosphere. This observation suggests that reduced Si species, Si(III) and Si(II), are responsible for the luminescence.

Arylazoimidazoles are important dyes which were intensively studied in the past. In contrast, triarylazoimidazoles (derivatives which carry aryl substituents at the imidazole core) received almost no attention in the scientific literature. Here, we report a new family of simple and easily accessible triarylazoimidazole-group 12 metal complexes, which feature highly efficient photo-luminescence emission (Φ up to 0.44). Novel compounds exhibit bright red emission in solution, which could be excited with a visible light.
