제목 Impact ofApplied Bias to Perovskite Quantum Dots in Various Surroundings
초록 All-inorganic CsPbX3 (X: Cl, Br, or I) perovskite quantumdots (PQDs) are one of key materials in next generation optoelectronic devicesand solar driven chemistry due to their outstanding photophysical propertiessuch as high photoluminescence quantum yield (PLQY, >90%), high absorptioncross section (> 105 cm-1), bandgap modulation, and soon. Our recent studies have elucidated that the PQDs are influenced by appliedbias to transform the precursor forms of the PQDs. The reason was that theinjected electrons and holes could induce the internal lattice strains so torelease the internal strain, irreversible transformation of the PQDs could be occurred.In this study we further moved on the effect of electron transport medium (ETM)to the PQDs placed under the electrochemical conditions. By soaking the excitedelectrons to the ETM, we further investigated the in-situ/ex-situphotophysical/material properties of the PQDs under placed in the applied biaswith contact to the ETM.
