  • The field of flat lens research brings innovative nanophotonic design concepts to the world of macro-optics. However, when evaluating the performance of these lenses a lack of consistency prevents proper comparison of competing technologies. This problem can be solved by using methods developed in industry for conventional lenses.

    • David F. P. Pile
    Q&A
  • Franky So, from North Carolina State University, explains some hard truths for solution-processed emitters, but also that, fundamentally, there is no reason why OLEDS can’t ‘make it’.

    • David F. P. Pile
    Q&A
  • Solution-processing of light-emitting devices is attracting much attention due to low manufacturing costs and access to new materials. In this month’s Focus issue we highlight some of the advances and challenges in the field.

    Editorial
  • Low stability of perovskite light-emitting diodes (PeLEDs) is the biggest obstacle to the commercialization of PeLED displays. Here, we cover the current status and challenges in analysing and improving the stability of PeLEDs and suggest some advice that will benefit the community to boost the operational lifetime of PeLEDs.
