High Optical Performance of Cyan?Emissive CsPbBr ₃ Perovskite Quantum Dots Embedded in Molecular Organogels

Perovskite quantum dots (PQDs) have fascinating optoelectronic properties, such as high photoluminescence yield (PLQY) for a broad range of materials, and the possibility to obtain different bandgaps with same material or halide combinations. Nevertheless, blue-emissive materials generally present limited PLQY color instability. Here, two molecular organogels, based on derivative an amino acid succinic acid, are used embed CsPbBr3 dots, obtaining green blue emission. Transmission electron microscopy (TEM) selected area diffraction (SAED) measurements performed confirm that there no significant changes in average size QDs crystal structure. A near-unity is achieved This contribution opens door postsynthetic treatment synthesizing PQDs optical performance, which can be attractive applications.
