Optical Examination of Transparent Nanocomposites Using Near-Infrared Light Sources
Abstract
This optical near-infrared (NIR) report covers efforts attempting to use transmitted wideband monochromic NIR illumination in investigating the nature of globular-appearing inclusions in five erbium (Er): yttrium oxide magnesium oxide nanocomposite specimens. Starting with the initial macro-image 1 findings, the report moves to discuss the chemistry and fluorescence generation of the nanocomposite ceramics examined. The microscopes hardware and software are then discussed. The test protocol section is brief. Results are divided into three sections, 850 nm, 850/780 nm, and 780 nm, with each specimen discussed separately. The issue of Er fluorescence and its imaging effects are noted. The summary attempts to identify common findings for both NIR wavelengths and discuss major differences. Conclusion discussions address the changes in initial premises and the utility of transmitted NIR in ceramics characterization.
