“…A major step forward to improving the reliability of luminescence age estimates was made with the development of optical dating techniques for quartz (Huntley et al 1985) and potassium feldspar (Hutt et al 1988), two of the most commonly occurring minerals on Earth. Zircons are another potential candidate for TL and optical dating, but technical difficulties have frustrated their routine use (Aitken 1998;van Es et al 2002).…”

Since the explorations of Alfred Russel Wallace and Eug�ne Dubois in the nineteenth century, Southeast Asia has been one of the world's focal points for studies of biogeography and biodiversity, human evolution and dispersal, environmental change, and the spread of culture, farming, and language. Yet despite its prominence, reliable chronologies are not available for many of the critical archaeological, evolutionary, and environmental turning points that have taken place in the region during the last 1.5 million years. In this paper, we discuss some of these chronological problems and describe how luminescence dating may help overcome them. "Luminescence dating" is a term that embraces the techniques of thermoluminescence (TL) and optical dating, which can be used to estimate the time elapsed since ubiquitous mineral grains, such as quartz and potassium feldspar, were last heated to a high temperature or were last exposed to sunlight. Luminescence methods have been successfully deployed at late Quaternary archaeological, paleoanthropological, and geological sites around the world, but not to any great extent in Southeast Asia. Here we describe the principles of TL and optical dating and some of the difficulties that are likely to arise in dating the volcanic minerals found throughout the region. We also outline several long-standing archaeological and paleoanthropological questions that are the subject of a current program of luminescence dating in Southeast Asia, and present recent dating results from Liang Bua in Indonesia and Bukit Bunuh in Malaysia.

“…Radiation effects as well as photoluminescence (PL), X-luminescence (XL) and thermoluminescence (TL) in zircon have previously been studied by various authors (1,2) . Optical absorption of zircon has previously been measured in relatively few works and mostly dealt with absorption in the IR region (3) .…”

“…A part of the studies concentrates therefore on the use of zircon in TL dosimetry and in dating of sediments. Some TL peaks in zircon fade, however, very rapidly close to the ambient temperature, due to recombination of trapped carriers with carriers of the opposite sign; the fading properties of a zircon sample have therefore to be carefully investigated, when considering it for TL dating (2) .…”

Irradiation effects were investigated in zircon crystals by methods of optical absorption and luminescence. Special attention was given to the effects of vacuum ultraviolet (VUV) radiation. The same main thermoluminescence (TL) peaks with the same thermal activation energies appeared after VUV as after X-or beta irradiation, indicating that the same traps were induced by the different irradiations. TL excitation spectra in the VUV showed an increase <220 nm and maxima near 190 and 140 nm. Excitation spectra of phototransferred TL (PTTL) and optically stimulated luminescence (OSL) were also measured. Most TL emission bands also appeared in the X-luminescence, PTTL and OSL. Dosimetric properties such as the TL radiation sensitivity, thermal stability of radiation-induced defects and TL dose dependence were also investigated. The radiation sensitivity of zircon was by an order of magnitude lower than that of TLD-100. The 355 K TL peak showed linear dose dependence only up to $500 Gy and the 520 K peak up to $1800 Gy.
