Application of a post-violet IR single-aliquot regenerative-dose (pVIR-SAR) protocol for natural polymineral fine and coarse-grain samples Open
Our group has previously characterised a post-violet infrared stimulated luminescence (pVIRSL) signal and developed a post-violet infrared single-aliquot regenerative-dose (pVIR-SAR) protocol for estimation of paleodoses. The protocol prov…

Luminescence Characteristics of Terrestrial Jarosite from Kachchh, India: A Martian Analogue Open
In this study, naturally occurring jarosite samples from Kachchh India (considered to be Martian analogue) were characterized using Fourier Transform Infrared Spectroscopy (FTIR), Cathodoluminescence- Energy Dispersive X-ray Spectroscopy (…

DFT Investigations of Major Defects in Quartz Crystal: Implications for Luminescence and ESR Dosimetry and Dating Open
Quartz is extensively used for luminescence and ESR dosimetry as well as dating. These techniques use inherent defects introduced in quartz crystal during its crystallization in nature. The defect comprises both intrinsic as well as extrin…

Investigating historical attribution: luminescence dating of bricks from a submerged structure in southeastern India Open
By 2019, a long brick platform with some structures was exposed when the Thamirabarani River, the southernmost river in the city of Thirunelveli, dried up. The civic society rejoiced at the discovery of the exposed structure as it was thou…

STUDY OF THERMOLUMINESCENCE CHARACTERISTICS OF QUARTZ FOR HIGH RADIATION DOSES (>1KGY): IMPLICATIONS FOR EXTENDING THE LUMINESCENCE DATING RANGE Open
Quartz is an omnipresent abundant natural mineral, used for luminescence dating. Lately, quartz optically stimulated luminescence (OSL) technique is widely used to estimate the equivalent doses (De) for dating geological events (up to 250 …
