煞费苦心

Journey of the Sun Among the Stars,tigators use a variety of systems for producing the CL and for recording the results, either as photographs or as spectra. Differences exist and the time seemed appropriate to begin to exchange standard samples on a large scale. Any interchange of standards in the past has been only among a small group of investigators.

Furthermore, feldspars are widely used as dosimeters in dating geological and archaeological materials by thermally or optically stimulated luminescence (TL, OSL).

Cosmology According to Aristotle,ists. CL has several advantages over PL, namely, a greater energy density and the possibility to focus the microprobe beam to a few microns (Marfunin 1994). In addition, CL only stimulates the surface, whereas PL stimulates the whole crystal zone excited by the laser beam.

Presently, better knowledge of the physical causes of CL and the use of CL spectroscopy has widened the application of CL in the geosciences. This new generation of CL instruments in combination with micro-scale, trace-chemical analytical techniques has a great potential for improving CL interpretations.

Cosmology According to Aristotle, the reconstruction of mineral-and rock-forming processes (Walker 1985; Marshall 1988; Remond et al. 1992). Investigations of gemstones by CL have especially focused on the evaluation of typomorphic properties to distinguish natural from synthetic gemstones (e.g. Gaal 1976, 1977; Ponahlo and Koroschetz 1985; Ponahlo and Brandstätter 1996).
