“…The typical change from initial blue to final brown CL colors was caused by the rapid decrease of the CL emission bands just below 400 nm and at 500 nm and the increase of the red emission band. This characteristic transient CL behaviour had been observed both in natural and synthetic hydrothermal quartz specimens (Götze et al, 2001).…”

“…Accordingly, this situation at low temperatures show an electrical charge changing reaction in the silica tetrahedral structure with developing strained Secondary alterations and re-crystallizations can often be easily recognized using CL. Thus, it is possible to reconstruct the mineral-forming processes or the trace mineral deposits (Götze et al, 2001). The spectral analysis of CL emission is an effective method to analyze the real structure of solids (Marfunin, 1979).…”

“…4-6). Götze et al (2001) have stated that the brown and reddish-brown CL colors (emission band at 620-650 nm) could also be explained by lattice defects induced by twinning, mechanical deformation, particle bombardment, or rapid growth. Another conspicuous (unusual) feature of quartz CL was the short-lived bottle green or blue CL in alpha-quartz, which is typical of quartz, crystallized from hydrothermal solutions.…”

Gem-quality green cryptocrystalline silica formation is relatively rare in nature, and has an interesting mineralogical crystallization and irradiation response of the fine fibrous silica. Chemical analyses of the green material reveal remarkable concentrations of some trace elements, such as nickel, iron, and chrome. They are certainly responsible for producing of the individual color production and irradiation luminescence response. Optical absorption spectroscopy shows that the dark green coloration is due to light transmittance at 528 nm in the visible region as a result of absorbance peak at 645 nm and about 360-410 nm absorbance band gap. These optical absorbance gaps are due to not only Ni ion content (4600 ppm) but also, Fe ion (13600 ppm) and Cr ion (823 ppm) contents. The cathodoluminescence spectra of the green material were taken into consideration in this study, and they were evaluated using "surpher, grapher, and axum" of the computer programs. In the spectra of alternative current cathodoluminescence with two-dimension, one major spectral emission band appears at readable intensity and magnitude in 90 Hz in the yellow wavelength region at 585 nm. In addition, the two-dimension cathodoluminescence spectra show that only the other major spectral emission band of cathodoluminescence appears at 90 Hz frequency in the green wavelength region at 530 nm.

“…Numerous workers have demonstrated the efficacy of cathodoluminescence~CL! spectroscopy in documenting the existence and details of such compositional variations in quartz~and other minerals!, as well as a correlation between Ti content and relative spectral intensity~e.g., Mason, 1987;Marshall, 1988;Götze et al, 2001;Peppard et al, 2001;Landtwing & Pettke, 2005!. However, quantitative use of CL intensity data is limited owing to uncertainties in their dependence on specific compositional and/or structural details. Other considerations include the difficulty in obtaining high-precision CL intensity data.…”

A Study of Cathodoluminescence and Trace Element Compositional Zoning in Natural Quartz from Volcanic Rocks: Mapping Titanium Content in Quartz

et al. 2012

Abstract:This article concerns application of cathodoluminescence~CL! spectroscopy to volcanic quartz and its utility in assessing variation in trace quantities of Ti within individual crystals. CL spectroscopy provides useful details of intragrain compositional variability and structure but generally limited quantitative information on element abundances. Microbeam analysis can provide such information but is time-consuming and costly, particularly if large numbers of analyses are required. To maximize advantages of both approaches, natural and synthetic quartz crystals were studied using high-resolution hyperspectral CL imaging~1.2-5.0 eV range! combined with analysis via laser ablation inductively coupled plasma mass spectrometry~LA-ICPMS!. Spectral intensities can be deconvolved into three principal contributions~1.93, 2.19, and 2.72 eV!, for which intensity of the latter peak was found to correlate directly with Ti concentration. Quantitative maps of Ti variation can be produced by calibration of the CL spectral data against relatively few analytical points. Such maps provide useful information concerning intragrain zoning or heterogeneity of Ti contents with the sensitivity of LA-ICPMS analysis and spatial resolution of electron microprobe analysis.

“…Cathodoluminescence (CL) is an effective method for detection of various types of emission centers (lattice defects and trace elements), and CL observation of several minerals has been applied in many geoscientific fields, e.g., observation of growth structure, interpretation of diagenesis and studies of sediments, evaluation of metamorphic and metasomatic processes in several minerals (e.g., Marshall, 1988;Götze et al, 2001;Gaft et al, 2005). In the case of zircon, emission centers are attributable to rare earth elements (REEs) and structural defects, of which combination results in a variety of luminescence color (e.g., Marshall, 1988;Blanc et al, 2000;Nasdala et al, 2003).…”

Cathodoluminescence of synthetic zircon implanted by He<sup>+</sup> ion

et al. 2017

View full text Add to dashboard Cite

He + ion implantation at 4.0 MeV, equivalent to energy of α particles from natural radioactive nuclei 238 U and 232 Th, has been conducted for undoped synthetic zircon. The cathodoluminescence (CL) of implanted samples was measured to clarify the radiation-induced effects. Unimplanted synthetic zircon shows pronounced and multiple blue emission bands between 310 nm and 380 nm, whereas the implanted samples have an intense yellow band at ~550 nm. The blue emission bands can be assigned to intrinsic defect centers formed during crystal growth. The yellow band should be derived from induced-defect centers by He + ion implantation, which might be related to the metamicitization originated from a self-induced radiation in natural zircon. The yellow band may be separated into two emission components at 1.96 eV and 2.16 eV. The emission component at 2.16 eV is recognized in both unimplanted and implanted samples, and its intensity increases with an increase in the implantation dose. The CL of zircon can be used as the geodosimeter.
