If Nanoco is going after graphene for light emission, it won’t be the first public company doing so. Dotz Nano (ASX: DTZ) has been working on and selling graphene for light emission, but the properties are not even close to those required for displays. Based on their website offerings, it appears as though most products have broad emission (70+ nm), poor efficiency (20-30%) and do not absorb blue light well enough to be considered for current LED displays. With these properties, I remain skeptical about the potential of graphene as a quantum dot substitute.
