a
Low light yields from fast crossover component and slow excitonic emission limit commercial use.
b
μs background emission component also seen below 70 K that would contribute to afterglow.
c
Measured with UV excitation. It has been reported that the decay time measured from RL excitation is slower, due to the additional excitation and cascade steps.79
