We are looking for phosphorescent (not fluorescent) micro-particles as a model system for light emission measurements in the case of diffuse light sources. Ideally the lifetime should be of several seconds up to minutes, and emission should be in the visible. Commercial solutions are much less than for the case of fluorescent particles.
Thank you.

Dear Giovanni,
Appended you can find a list of AG phosphors and some literature.
All the best for your research!

Ciao Giovanni,
In our paper here you will see that its possible to tune the lifetime of the emission without necessarily sacrificing the brightness of the long-lived luminescence - we were targeting the seconds range:
