Abstract
Uranium compounds have been used to give glass a fluorescent shining green color for hundreds of years. Such glass has been found in daily use articles as well as in optical filters. We have come across its interesting properties looking for a nearly first order volume scatterer, which, after initial reflection, does not provide significant multiple scatter. The basic idea was to excite a fluorescent material under geometrically well defined conditions and use the pattern of the emitted light as a model for volume scatter. Although it is obvious that the basic mechanism is different from scatter, the obtained pattern is useful for device calibration and investigations on imaging devices for semitransparent scattering or self emitting materials. In the current paper some mostly experimental investigations on a variety of uranium glass are presented, questions of its usability as a volume scatter and emission standard are discussed. With special regards to the conference - a historical review on the topic is given.
