Modernization and Automation of Gemological Testing: Harnessing the Power of Laser-Induced Spectroscopy for Raman, Photoluminescence, and Photoluminescence Lifetime Analysis

Abstract

The chapter explores the revolutionary application of laser-induced spectroscopy in the field of gemstone analysis. It highlights the use of advanced techniques such as Raman spectroscopy, photoluminescence, and photoluminescence lifetime analysis, which have proven instrumental in identifying a variety of gemstones such as corundum, spinel, emerald, alexandrite, etc. This state-of-the-art technology stands at the forefront of differentiating natural from lab-grown materials, discerning treatment methods, and determining the origins of significant colored gemstones. This chapter provides an in-depth view of the practical implementation of emission spectroscopy in the analysis of colored gemstones, shedding light on its integral role in the rapidly evolving gemological testing systems. The goal is to furnish readers with a thorough understanding of how these advanced methods are transforming gemstone analysis, contributing significantly to the industry’s quest for enhanced precision and accuracy.
