"could be instrumental in the future development of micro LED arrays consisting of a single material... could lead to a more rapid phasing out of non-solid-state lighting sources – such as incandescent bulbs – and even the current phosphor-coated blue InGaN LEDs with a fully solid-state color-mixing solution, in turn leading to a significant reduction in global energy consumption... can be widely adopted and implemented at scale"
