Abstract

Organohalide perovskite nanocrystals (OHPNCs) and their wide range of optoelectronic applications have attracted much interest due to their unparalleled photoluminescent intensity and quantum efficiency. Furthermore, their band gap is tunable over the visible and near-infrared wavelengths through changes in composition, shape, or size. However, OHPNCs are unstable under ambient conditions due to their high reactivities with moisture and gases. In this work, the stability of methylammonium lead iodide (MAPbI3) perovskite suspension and dried films against heat and water was enhanced through the addition of tetraethyl orthosilicate (TEOS). With the SiO2 coating, the photoluminescence (PL) of MAPbI3 nanocrystals increased by 30% and the MAPbI3 films were stable in ambient environment for several weeks. The enhancement of stability can be further improved by adding the TEOS in steps and increasing the time interval between the steps. Furthermore, the silica-coated MAPbI3 perovskite nanocrystals were made into photodetectors demonstrating their practical applications in ambient condition.
