Metal Halide Perovskites (MHPs)

MHPs are a rising star in optoelectronics which are suitable materials for solar cells (well... mostly) and LEDs. Currently, these materials are looking fowards to the commercialization. Let's see how the smarties all over the world can get away from the toxicity and intrinsic instability of MHPs. 

p.s. If anyone wants to get some tips regarding vacuum thermal evaporation of MHPs, please do contact the responsible researcher

Metal Organic Chalcogenide (MOCs)

MOCs have been investigated since 1991, mostly to understand the structural property. Fortunately, Hohman group found out that AgSePh shows super sharp blue emission and remarkable chemical stability which is attractive for LED application. Yet, the PLQY is too low for that. The very same research group reported silver sulfide MOCs with methyl thiosalicylate ligand with higher PLQY. So, the responsible researcher employed vapor-assisted solution process to get thin films and integrated into LEDs (namely MOCLEDs) for the first time.

Pathfinding!

There are still quite many materials hidden which might show very unexpected properties. Always, exploring new candidate is fascinating work indeed.
