Characterizing the distribution of trace elements in many advanced solid materials can be analytically challenging and time-consuming. 3D-LIBS (Laser Induced Breakdown Spectroscopy) is a powerful, rapid, quasi-simultaneous, and indirect micro-sampling technique that can identify and map any element (including light elements and gases) to 1 ppm, in most solid materials. Sample surfaces can be mapped over a variety of spatial scales, from 10’s of microns to centimeters, with depth resolutions of 100’s of nanometers to 10’s of microns.
We investigate a range of materials for trace element distributions in film/coating/substrate interfaces or treated/exposed surfaces. Examples include, i) H, O, B, S and Ti in Ni superalloys, ii) O, H and alkali elements in high purity Al metal, iii) refractories in high refractive glasses, and iv) Li and metal distribution in Li battery electrodes.
