Response to “Critical Growth Temperature of Aqueous CdTe Quantum Dots is Non‐negligible for their Application as Nanothermometers”

Researchers responded to the findings of the paper entitled 'Critical Growth Temperature of Aqueous CdTe Quantum Dots (QD) is Non-negligible for their Application as Nanothermometers'. This study was motivated by earlier published article in Small entitled 'CdTe Quantum Dots as Nano-thermometers: Towards Highly Sensitive Thermal Imaging'. The authors reported that the thermal sensitivity of the CdTe QDs that they synthesized was size-independent for three different capping agents. New QDs were ordered from Plasmachem Inc., and the thermal sensitivity of QDs of different sizes was measured to explain the differences. A linear relationship between the emission wavelength and size was obtained for QDs of size 4.7 and 3.8 nm. Researchers responded that the inner lattice expansion/contraction of QDs was a key factor in determining their characteristic thermal sensitivity, which was modified by the presence of strong and directional surface forces caused by the different capping agents.
