Optical Spectroscopy Laboratory

The laboratory is fully equipped for conducting comprehensive characterizations of luminescent materials in the form of powders, solutions, or thin films. The laboratory is designed to provide measurements of emission and excitation spectra, decay times and determination of quantum yields.

The special structure of the laboratory ensures preparation of projects dedicated to the needs of customers, allows supervision over scientific and research works related to optical materials that have a specialized application in various areas, from modern lighting (e.g. of LED type); through anti-counterfeiting marking, to advanced medical technologies.
