Facts (generated by robot; please edit if you find it inaccurate)
- Introductory Concepts - Fluorescence is a member of the ubiquitous luminescence family of processes in which susceptible molecules emit light from electronically excited states created by either a physical (for example, absorption of light), mechanical (friction), or chemical mechanism.
- A baseline of fluorescence is collected (1) before the photobleaching occurs (arrow) so that the amount of fluorescence is reduced significantly (2).
- So how can fluorescence help in identifying minerals? Well, fluorescence is not a common phenomenon being found in only certain minerals.
- Fluorescence is a process distinct from incandescence, which refers to emission of light from an object heated to such high temperatures that it glows.
- The relative intensity of the fluorescence is measured at the various wavelengths to plot the emission spectrum, as illustrated in Figure 1(b).
