Autunite Visible Spectra (400
- 1000 nm)
Autunite, Ca(UO2)2(PO4)2ยท10-12H2O, owes its color to the UO22+
ion,

spectrum;
from the Daybreak Mine near Spokane, Washington, USA, 0.092 mm thick
sample. This mineral contains the UO22+
ion which is responsible for all the structure in the
spectrum.
The spectrum was obtained in the E perpendicular to c
direction on a cleavage plate.
