Some Stable Fluorescent Converter Solutions Enhancing Optical Pumping in the Visible Region

A series of fluorescent converter solutions is described, increasing the radiation intensity of flash lamps in the region 4000–6000 Å with a factor RΛ1.5˜3. The converter solutions are composed for use at an optical path of 1 cm, are easy to prepare, and are stable under high intensity irradiation with u. v. and visible light.
