Pb-free Cs2SnI6 perovskite nanoparticles with different morphologies are synthesized using hot injection process and precise control of ligand chemistry. Size dependent band gap variation is studied to evaluate quantum-confinement effect in the system. Stable and fast photodetector with high current gain is fabricated by using the nanoparticles as colloidal ink.
