Materials and Methods,he purpose of introducing the respective employed materials and methods. Firstly, a typical perovskite NC synthesis is described, followed by an introduction to the different NC compositions and morphologies that may be achieved. Next, the three lasers used most commonly in the experiments for this

Recombination,nding interband relaxation of e-h pairs and excitons in particular was studied for the case of quantum-confined CsPbBr. nanoplatelets with a tunable thickness. First and foremost, this material was characterized and specifically modified in order to obtain an efficient blue emitter suitable for the

Dephasing,le, studies so far rarely distinguish between homogeneous and inhomogeneous transition broadening. This may be of particular interest for NCs, as inhomogeneous broadening may also serve as an indicator for the homogeneity of an ensemble of NCs. In this chapter, first, the total transition broadening
