Description

The effect of polyvalent dopants on photoinduced defect formation was studied in different glasses. Ionisation of the glass matrix results in intrinsic defects, positively charged hole and negatively charged electron centres. Polyvalent dopants can be photooxidised or photoreduced. These extrinsic defects might replace selectively one or several intrinsic defects and/or cause an increase in the number of opposite charged defects. Photoionisation can also result in unusual dopant valences otherwise not observed in glasses. The systematic comparison of different dopants and glass systems irradiated by excimer lasers helps to understand defect generation processes and might eventually help in the design of UV-resistant or UV-sensitive glasses. Defect formation occurs in the ppm range and was analysed by optical and EPR spectroscopy. A series of polyvalent dopants such as typical trace impurities, glass or melt additives and typical dopants used for optical components like filter glasses, optical sensors, fluorophores or photochromes, were studied. Distinct melting conditions give rise to different valences of various dopants and as a consequence different photoinduced redox-reactions might be observed after irradiation. Some dopants are photooxidised while others are photoreduced Some defects recombine easily or transform into more stable defects while others are stable for months or years.
