Detailed Description

This expanded collection allows a study in detail of the response of these minerals to the range of ultraviolet rays. 15 specimens approximately 1 1/2" 1 1/2".
Fluorescence is the emission of light that some minerals exhibit when exposed to ultraviolet light.
Long wave and short wave ultraviolet lights are commonly used to cause fluorescence.
The short wave light is higher frequency light than the long wave light.
This difference in frequency causes the electrons to behave differently and thus may emit different color fluorescence.

The incoming ultraviolet light is absorbed; causing weakly held electrons in the crystal lattice to jump to higher energy levels. When the electrons settle to their original stable energy levels, energy is given off as fluorescence.

Weakly held electrons may result from atomic substitution (impurities) in the atomic structure or may be present without substitution.
