Technical Information: Publication of 'Evaluation of Material Structure of Organic EL (OLED)' and two other items.

It is possible to identify components for each layer, pixel by pixel.

To improve the reliability of organic EL, which is expected to expand in demand in the future, detailed structural analysis, state analysis, and identification of degradation causes will become increasingly important. We will introduce examples of evaluating layer structures and materials using TOF-SIMS and LC/MS. With TOF-SIMS, we were able to evaluate the layer structure and the component information of each layer. We conducted analyses of the components revealed by TOF-SIMS using LC/MS and a fluorescence detector, allowing us to assess the emission wavelength and understand the structure of the components. Thus, the combination of TOF-SIMS and LC/MS enables detailed evaluations.

It is possible to evaluate the distribution of the crystalline state of carbon within the sample surface.

Carbon materials, widely used in industrial components and medical devices, have different properties depending on their structure and crystallinity, making it important to evaluate their state. This document presents evaluation examples using high-sensitivity and high-spatial-resolution Raman spectroscopy. The distribution of the crystalline state of graphite, a carbon material, was visualized through mapping. It allows for a visual capture of the quantity of defects, whether high or low.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
