Synthesis and Surface Chemistry of Phase-Stable Caesium Lead Halide Perovskite Colloidal Nanocrystals

All inorganic CsPbX3 (X=Cl-, Br-, I-) perovskite nanocrystals possess near-unity photoluminescence quantum yield , narrow PL peak full width half maximum, and fully tuneable emission across the entire visible spectrum. As a result of these superb properties, these materials have emerged as promising candidates for a variety of optoelectronic applications. Yet, the understandings towards the synthesis of this material class is still limited. Therefore, the aim of this thesis is to further investigate the synthesis of CsPbX3 NCs with an overarching goal to developing phase stable CsPbX3 PNCs that can be assembled and used within practical applications.
