Abstract:

In the contract period covered by this report a series of photochemically stable fluorescent converter solutions has been composed. At the beginning of the contract period some new stable UV transmitting solution filters were developed and with these photo-stability of the converter solutions could be studied under irradiation with high intensity UV light only. The results of the investigation concerning the UV transmitting filters has been reported earlier and is now available in print. Applying the converter solutions in combination with large energy linear flash lamps the relative increase R lambda of the intensity of the incident light on the irradiated system has proved to be of the order 1.5 - 3 in the region 4000 - 6000 A, when a total electrical energy of 5.6 kJ was discharged through the lamps. By filling the inner tube of a double jacket quartz cell with 0.3 Ludox suspension and placing the cell between two linear flash lamps, the R lambda values were determined measuring the intensities I lambda, H2O and I lambda, conv of the scattered light coming from the inner tube, while the annular space was filled with water and converter solution respectively.
