To physicists and chemists, color means light emission, absorption, spectrum, and coloration. Near-Infrared Organic Materials and Emerging Applications presents knowledge and applications of invisible "colored" organic materials. Near-infrared (NIR) materials are defined as substances that interact with NIR light, namely, absorption and reflection, and emit NIR light upon stimulation, for example, photoexcitation, electric field, and chemical reaction. This book offers up-to-date information on low band-gap organic materials with unique near-infrared absorbing, fluorescent, and...
