Luminescence, fluorescence and phosphorescence of …
In 1943, De Ment identified the uranium luminescence spectrum of calcite from Deming, NM, USA under SW and the Terlingua, Texas, USA calcite. For Terlingua calcite, he found a strong band at 410-450nm (purple-blue), a bright green band at 450-545nm and a weak reddish band at 545-620nm. The blue long-lived phosphorescence have the same spectral ...
