Perovskite quantum dots (PQDs) are now emerging as functional materials for many photonic applications due to their superior optical properties and easy fabrication. In 2015, we report ligand-assisted reprecipitation (LARP) of brightly luminescent and color tunable perovskite quantum dots. In 2016, we reported the in-situ fabrication of PQDs in polymeric films with high transparency, superior photoluminescence emission and additional processing benefits for down-shifting applications. The potential use of in-situ fabricated PQDs as color converters in LCD backlights was successfully demonstrated, showing bright potential in display technology. Very recently, we developed the in-situ fabricated PQDs patterns for Micro LED and other down conversion applications. In addition, we also demonstrate the use of in-situ fabricated perovskite quantum dots for other applications including UV enhanced silicon photodetectors, photovoltaics, quantum dots based hyperspectrometer, CW laser etc. In all, the in-situ fabricated PQDs provide promising functional materials for many photonic and optoelectronic applications.
