Ethanol-processable CaF2 nanocrystals for high-performance and low-index antireflective coatings.

Reflection at glass/air interfaces remains a major source of optical loss in transparent optoelectronic devices, which can be effectively mitigated by introducing antireflective coatings based on low-refractive-index materials. Calcium fluoride (CaF2) is an excellent candidate due to its intrinsically low refractive in...
