Existing optical thermometers are faced with the challenges of high sensitivity limited to a very narrow high temperature range, while also lacking low temperature sensing performance. A new linear up-conversion...
A SnO2–SnO hybrid nanostructure with p–n heterojunctions exhibits enhanced sensing performance for NO2 gas detection with high sensitivity and selectivity.
A ratiometric and colorimetric thermometer with high sensitivity and significant color change from 50 to 300 K has been developed by encapsulating the luminescent dye 7-diethylamino-4-methylcoumarin (C460) into the channels of a terbium-based MOFTbTATAB.
