From a silver ore at Maikain, Kazakhstan, fluorescence is blue under LW.

From another silver ore location in Kasmanchi, Uzbeckistan, a bromian Chlorargyrite (Embolite?) fluoresces green under LW.

Comments on activators and spectra:

Silver halides are capable to intrinsic luminescence.


It was found by steady-state luminescence spectroscopy that silver halides, such as chlorargyrite and embolite, demonstrate luminescence at low temperatures.

Such emission was explained in energy band scheme by donor-acceptor recombination.

Under powerful laser excitation, such luminescence was detected even at room temperature.

The spectra are evidently connected with the same luminescence centers (Gaft et al. 1989).

Laser-induced time-resolved luminescence spectrum of chlorargyrite demonstrates a relatively narrow green band with short decay time of ~2–3 μs (Gaft).
