The pseudo-colour panels represent 10 s of accumulated luminescence. Often, there is a gradational transition in luminescence from weak to stronger, followed by an abrupt return to weak luminescence. The central chapters contain information about luminescence centres, categorized according to centre type. Luminescence of aequorin is triggered by the binding of two calcium ions. His eyes glow; his long, slender fingers are like tongues of flame; the colour of his skin is more a luminescence than a colour. This panel represents 60 s of accumulated luminescence. Nevertheless, this is an important volume that students of luminescence in mineralogy will value. This irradiating process induces a luminescence in the visible wavelength. It includes a discussion of the benefits of time-resolved luminescence as against continuous excitation - an important and expanding field. The iris is checked for pupil size, constriction, reflected luminescence, and synechia. Alternatively, the variations in trace element abundance and luminescence may be simply coincidental and crystal lattice defects related to growth rate may be playing an important role. Some substructure can be observed on the images of the compressed core luminescence, though the appreciable asymmetry of the form has been detected in only one experiment.
