Introduction
摘要
Trivalent rare-earth-ion (REI)-doped glasses are pivotal materials driving innovation in modern technology, from high-speed telecommunications and solid-state lasers to optical sensors, nanophotonics and others. Their unique ability to emit light in almost the UV, visible and near-infrared regions and being molded into various forms makes them indispensable. This book serves as an essential guide, detailing the spectroscopic techniques and data interpretation methods needed to reveal the potential of REI-doped glasses and drive future innovation.
