Multi-colored fluorescent specimen under shortwave
ultraviolet (left), and midwave ultraviolet (right).
Tugtupite is here bright pink under SW and bluish-pink
under MW. Sodalite is orange under both
sources but of differing intensities. Note the band of yellow-white
fluorescing polylithionite in lower
right of shortwave photo, does not fluoresce under midwave ultraviolet.
Luminescence spectra of the green and blue fluorescing phases show peaks characteristic
of uranyl activation. |
