Re: "Proof of Principle" for True White Emitter
IMO
this article has a more accessible explanation.
Quoting from this linked article:
"Previous attempts using the same basic concept involved linking together two separate molecules into one. But, because energy is able to flow between the two molecular sub-units, one unit typically emits more light than the other, resulting in an unwanted tint. The new molecule does not suffer that problem, and only contains one light-emitting chemical group. When connected to a voltage, this group switches to a high-energy form that emits blue light as it reverts to its original state.
Roughly half the time, though, the high-energy form picks up extra oxygen and hydrogen atoms, becoming a short-lived form that produces orange light before reverting to the original state.
A large population of the molecules reliably produces equal quantities of orange and blue light that mix to produce an even white."
This explains why this molecule is 'better' than previous ones, but note that it has a long way yet to go. Compared to current LED phosphors, it is only 1/30 of the efficiency.
