Which outcome occurs when an organic LED's emission frequency nears the transport band edges?

💡 Explanation

Decreased radiative recombination efficiency occurs because band edge states exhibit lower radiative rates due to a decrease in the density of states available for radiative recombination, which causes non-radiative processes to dominate therefore decreasing efficiency, rather than enhancing emission under optimal conditions.
