Phosphorescence (in the common sense of the term) observable with the naked eye:

No phosphorescence visible to the naked eye under any type of UV

Comments:

Said to be not fluorescent in the original describing paper, tough, a perfectly determined specimen shows a clear longwave fluorescence with a typical uranyl spectra.

Also clearly fluorescent under 405nm pointer laser
