The laboratory is suited to perform synthesis of materials with well-designed luminescent properties. Next a comprehensive characterization of their luminescent properties and a composition analysis can be made. These materials have applications in various areas, from modern lighting (e.g. of LED type), through anti-counterfeiting marking, to advanced medical technologies. The Luminescent Materials Laboratory consists of modern equipped laboratories of Organic Synthesis, Inorganic Synthesis, Special Synthesis Methods and Clean Synthesis. In these laboratories there is possible to synthesize organic compounds, rare earth based complexes and materials as well as nanoparticles. An available equipment allows to carry out reactions in solution or in solid phase using a conventional thermal heating or microwave irradiation, at reduced or elevated pressure. Microwave reactors allow to perform up to 10 reactions at the same time. Glove boxes allow to obtain compounds requiring an inert atmosphere during the synthesis. A preparation of different samples, as for example industrial samples, pharmaceutical, or environmental ones for analysis can be performed using a multi- task apparatus for the extraction, spray drying, vacuum drying and lyophilization. A post reaction heat-treatment can be performed in high-temperature furnaces. A full spectroscopic characterization of obtained substances can be made in Optical Spectroscopy Laboratory, which is a part of Luminescent Materials Laboratory.
