Abstract

Metal halide perovskite nanocrystals with the chemically tunable bandgap and superb optical properties are promising candidates for a number of high performance optoelectronic and photonic applications. The majority of studies on perovskites have focused on the large perovskite nanoparticles in the weak confinement regime, however recent synthetic advances have allowed for the preparation of high quality 0D, 1D, and 2D confined perovskites, both hybrid organic-inorganic and all-inorganic. These new synthetic methods have enabled the study of confinement effects on various photophysical properties of perovskites nanocrystals previously not possible. In the first section of this chapter, we discuss the synthetic methods for the preparation of both hybrid and all-inorganic perovskite nanocrystals in the strong confinement regime, including the synthetic protocols as well as the mechanistic aspects of the nanocrystal growth. The second section discusses the confinement effects on various static and dynamic photophysical properties of exciton experiencing varying degree and dimensionality of quantum confinement.
