Abstract
Hybrid and inorganic perovskite nanocrystals are a hot topic in materials chemistry due to their versatile optoelectronic properties. Herein, we report highly luminescent water stable lead-free orange emissive (OleylAm)2SnBr4 (OleylAm = oleylammonium cation) 2D tin halide perovskite nanocrystals in humid conditions in a solution-based process. The photoresponse study performed with the synthesized nanocrystals exhibits a responsivity of 4.9 mA W-1 at a 5 V operating voltage.

Abstract
Lead halide perovskites with high fluorescent and tunable morphology appeared at the forefront of materials chemistry because of their corresponding impressive optoelectronic properties. The current advancement of metal halide perovskites put forward the functional and bidentate ligand to expand their utilization in modified ligand chemistry. We successfully introduced nontoxic aromatic amino acid as a capping ligand to synthesize the perovskite nanocrystals (PNCs). The implementation of aromatic amino acid for the construction of CsPbX3 nanocrystals (NCs) provides the synergetic service of the carboxylic and amine groups with the phenyl residue, which prompts the formation of NCs with high fluorescence intensity. The experimental results demonstrate the emissive property of PNCs in a whole visible region with long-term stability. Additionally, the morphology of the NCs has been tuned. We performed several characterization techniques to investigate the nature of the NCs in the solid and solution phases.
