Halide perovskite nanocrystals (NCs) have emerged as an intriguing material for optoelectronic applications, most importantly for light-emitting diodes (LEDs), lasers, and solar cells. Despite exhibiting impressive properties such as quantum yields of nearly 100%, narrow emission spectra, and strong absorption, wide-spread commercialization has been impeded by some (critical) issues. In this talk, I will focus on two of these issues, a reduced emission in the blue spectral range and strong susceptibility to degradation. We have developed a perovskite NC system to tackle each of these two problems separately. For enhanced blue emission, we investigate two-dimensional nanoplatelets (NPls), whose reduced thickness induces considerable quantum confinement.[1] NCs encapsulated with block copolymer micelles are explored for enhanced stability.[2] I will show the benefits of both types of NCs and offer pathways for implementation into optoelectronic devices.
