摘要: The investigated mixtures were also flashlamp-pumped . exciting pulse energy was 200 J, its length ~ 3 #sec, and rise time 1.5 ]~sec. We consider the processes occurring in solutions case of laser excitation. Figure la (curve 5) shows lasing efficiency an ethanol solution oxazine 17 as a function concentration. threshold attained at concentration 5 * 10 -5 mole/liter, maximum (~ 13%) observed high cmcentrations - 5-6 �9 -4 mole/liter. emissionband shiRed from 649 to 658 am when changed -3 To determine optimal conditions for we considered it interest investigate effect donor on accepter efficiency. relations obtained two systems are shown Fig. lb. At fixed concentrations (10 mole/liter)
