Charoite: Silicate Mineral with Luminescence Properties

June 26, 2021 Chemistry and Biochemistry 0

Charoite luminescence measurements were carried out, with the two main emission bands centered around 380 and 600 nm. Heat pressure and, more importantly, the infusion of specific chemicals into the rock cause the transformation into new minerals such as charoite. There are minor differences in reaction between cathodoluminescence and radioluminescence, but there are significant differences between light and dark charoite. In a dark sample, there is an additional band near 820 nm with a discontinuity in intensity near 170oC. This feature is thought to be caused by the loss of water bonded to the structure. This gem stone’s emission bands are modelled in a way that is consistent with previous proposals.
