Lead halide perovskite (LHP) semiconductors show exceptional optoelectronic properties. Barriers for their applications, however, lie in their polymorphism, instability to polar solvents, phase segregation, and susceptibility to the leaching of lead ions. An international team of researchers (Australia, Slovenia, China, UK, France, Japan, Singapore) has developed a process to wrap or bind the nanocrystals in porous glass to stabilize the material, enhance its efficiency, and inhibit the toxic lead ions from leaching out from the materials. The product showed high stability when exposed to heat, light, air, and humidity, and was able to retain 80 percent of its luminescence after 10,000 hours of water immersion. According to the researchers their work would benefit all aspects of perovskite research not only for its use in electronic displays but also for solar panels…read more. TECHNICAL ARTICLEÂ
