Optofluidic Sensor: Evaporation Kinetics Detection of Solvents Dissolved with Cd₃P₂ Colloidal Quantum Dots in a Rolled‐Up Microtube

A method for measuring the evaporation kinetics of pure solvents and solutions containing Cd3P2 quantum dots (QDs) in SiO/SiO2 rolled-up microtube (RUT) resonators is reported. The QDs serve as wavelength-tunable fluorescent sources for the RUT resonator. The first-order kinetic constant (295 K) of the evaporation of toluene embedded in a RUT (D = 9.10 μm) is evaluated (0.055 min−1).
