Perhaps related, we observe a strong excitation-wavelength dependent photoconductivity in TRMC experiments, as summarized in Figure . Both behaviors are extremely unusual, as typically one expects higher excited states to relax to the band edge on an ultrafast timescale, leading to excitation-energy independent emission and photoconductivity. Even more surprising is that the photoconductivity at 355 nm excitation is lower by a factor of ≈5 relative to 600 nm excitation; yet, the carrier lifetime is longer by a factor of ≈ 2× with 355 nm excitation. Ordinarily higher excitation energies could only lead to higher photoconductivitives due to hot carrier or impact ionization that could multiply photoexcited carriers. Taken together, these observations suggest the presence of a higher lying excited state that is decoupled from the the ordinary band structure, leading to bright localized emission and a low probability of forming free mobile carriers.
