A facile one-pot synthesis of deep blue luminescent lead bromide perovskite microdisks

摘要

We report a facile one-pot synthetic method to prepare highly luminescent layered lead(II) bromide perovskite microdisks with the lateral size of a few micrometers and thickness of 100-150 nm, featuring narrow deep blue emissions with quantum yields of up to 53 in toluene solutions and thin films at room temperature.
