“…In contrast, in a good pressure medium environment, the band gap continued to increase. This result could inspire the invention of pressure probing applications with widely tunable responding behavior by embedding QDs in a properly chosen polymer matrix . On the other hand, the kinetics of the pressure also influences the pressure response of QD band gap.…”

“…This result could inspire the invention of pressure probing applications with widely tunable responding behavior by embedding QDs in a properly chosen polymer matrix. 281 On the other hand, the kinetics of the pressure also influences the pressure response of QD band gap. The band gap of CdSe QDs was found to be less sensitive to shock impact than continuous pressure.…”

Nanoparticle (NP) high pressure behavior has been extensively studied over the years. In this review, we summarize recent progress on the studies of pressure induced NP phase behavior, property, and applications. This review starts with a brief overview of high pressure characterization techniques, coupled with synchrotron X-ray scattering, Raman, fluorescence, and absorption. Then, we survey the pressure induced phase transition of NP atomic crystal structure including size dependent phase transition, amorphization, and threshold pressures using several typical NP material systems as examples. Next, we discuss the pressure induced phase transition of NP mesoscale structures including topics on pressure induced interparticle separation distance, NP coupling, and NP coalescence. Pressure induced new properties and applications in different NP systems are highlighted. Finally, outlooks with future directions are discussed.

“…As the temperature of the QDs increases, the heat, thermally quenches the core of the QD, reducing the luminescent properties of the sample. The decrease in irradiance is likely due to the increased thermal activation energy which would active the trap states and also increase non radiative Auger recombination [10]. The degradation increases with temperature, more dramatically at 200°C.…”
