Four samples have been studied under polarised light and under
cathodoluminescence: fresh rock is represented by Sample II-1; slightly weathered rock is represented by Sample II-3; moderately weathered rock is represented by Sample II-4; and intensively weathered rock is represented by Sample VIII-3.
Calcite is stained red in thin section and bright yellow under
cathodoluminescence (CL).

Cathodoluminescence images show growth zonations within certain sparry calcite crystals, but dull to nonluminescent sector zonations are mostly observed (Figure 4).

This works on the same principle as
cathodoluminescence imaging.
Advanced Materials represents the culmination of 10 years of research undertaken to develop a consistent and feasible procedure for the quantitative assessment of ceramic surfaces in joint implants on the molecular level through Raman assessments of ceramic and polyethelene bearings to support the
cathodoluminescence approach.
Neodymium ion doped lutetium fluoride ([Nd.sup.3+] :Lu[F.sub.3]), whose
cathodoluminescence (CL) efficiency is almost equivalent to KMgF3, was selected as a phosphor to develop a new VUV lamp.
