Quartz plays a crucial role in retrospective dosimetry and dating inquiries in Quaternary
Science. The success of thermally and optically stimulated luminescence (TL, OSL) methods …

The mechanism governing the production of the paramagnetic [AlO 4/h+] 0 centres (denoted
also as Al-hole or Al-h) in quartz as a function of given dose is of great importance in …

In this paper, we present the results of research on the thermoluminescence (TL) and optical
absorption (OA) properties of colorless natural quartz (including natural quartz samples …

As part of a general study of the thermoluminescence (TL) of quartz, we have examined the
3-D spectra of samples of quartz extracted from a variety of sediments. Blue emission at …

A fase estável da sílica (SiO2) à temperatura ambiente, conhecida como quartzo-α, é um
dos minerais mais abundantes da crosta terrestre, cerca de 12%(Frondel, 1962). Ela ocorre …

Gemstones of the quartz group display a wide spectrum of colours, both natural and those
colours produced by artificial enhancement. Colour modification methods such as heat …

This study investigates the origin of point defects involved with a strong sensitization of the
thermoluminescence (TL) signal of natural quartz between 220 and 400° C. The …

This paper describes the manufacturing process of quartz-pellets and shows their potential
use as thermoluminescence dosimeters (TLD) for those applications where low-levels of …

This article reports the sensitization of the glow peak at 300° C in crystalline quartz by using
high doses of gamma radiation. Five lots of samples were prepared from single crystals …

This paper discusses the structural features required to stimulate a strong
thermoluminescence (TL) glow peak near 300° C in clear natural quartz. For that reason …
