Use of disk phosphoroscopes.
With the help of operational calculus, an effort is made to give the best conditions for the use of disk phosphoroscopes for measuring phosphorescence decays as well as for spectral measurements. This method, which up to now was only used for monomolecular processes, can be applied to any kind of process. We have been able to define limits both for the use and validity of several photometric and photographic experiments. Our results show what kind of apparatus is the most appropriate and how each measurement can be used in relation to the quantity to be found, whether it be the population of traps or the photometric efficiency of phosphorescence processes.
