Ultrafast vibrational relaxation and hot luminescence of Tl+ centers in Kl
Zavt G.S., Plekhanov V.G., Khizhnyakov V.V., Shepelev V.V.
Hot luminescence bands are observed in KI-T1 crystals. These bands are interpreted as emission from the first classical turning point in the process relaxation of the configurational coordinate, which represents a complex nonmarkovian process with scale time —0.5 ps.
