Photoluminescence Investigation of Purified and Non-purified Methylammonium Lead Halide Perovskite Nanocrystals

To date, methylammonium lead halide perovskite nanocrystals are outstanding materials in terms of application possibility in optoelectronics. Nevertheless, they are unstable under ambient conditions and sensitive to various polar solvents. Hence, colloids purification steps are hampered. Here, we re...

Description
Summary:To date, methylammonium lead halide perovskite nanocrystals are outstanding materials in terms of application possibility in optoelectronics. Nevertheless, they are unstable under ambient conditions and sensitive to various polar solvents. Hence, colloids purification steps are hampered. Here, we report a purification technique of perovskite nanocrystals using aprotic polar solvent ethyl acetate.
