"avoids very high temperature, lots of energy. bulk,.. colloidal quantum dots in solution spin coating/ printing... also records IR phase/ interference... smart textiles for firefighters/ patient monitoring/ fashion, motion detectors, chemical analyzers, satellites... silicon-based lidars with measured 905 nm IR would be harmful at high power, so only emit weak light, which limits system's range, and those for longer, safer wavelengths too expensive, but faster quantum dot detectors could provide safe/ cost-effective lidar"
