This article discusses the prospect of advanced functionalities in the field of nanocrystal optoelectronics using structured photonic environments, with a particular emphasis on near-infrared light-emitting diodes. The ability to achieve full control of brightness, colour, phase and polarization is highlighted, as well as the importance of determining whether a local or non-local photonic response is required to achieve a given functionality. These developments have implications for various applications, including displays, communication protocols and sensors.
