WebApr 10, 2024 · Monodispersed CsPbBr 3 (CPB) QDs obtained in water show high photoluminescence quantum yields (PLQYs) of 86.4% and their PL features of CPB QDs have no significant change after being dispersed in ... WebTernary CuInS2 quantum dots (QDs) with photoluminescence tunable from the visible to near-infrared (NIR) region are promising light-emitters for consumer electronics due to the absence of toxic elements such as Pb, Cd or As. Despite the compelling performance of visible emitting CuInS2 QDs, reports on NIR emission remain limited with modest ...
