The S.I. Vavilov Luminescence Department (originally the Luminescence Laboratory) was established by academician S.I. Vavilov simultaneously with the creation of the FIAN in 1934. The Vavilov-Cherenkov effect was discovered in the Department (Nobel Prize in 1958), the first domestic laser was created (chl.-corr. RAS M.D. Galanin). The main research areas of the Luminescence Department are photo- and electroluminescence of various organic, inorganic and hybrid systems. Fundamental problems of energy transfer of electronic excitation and charges in low-dimensional systems (colloidal quantum dots of different compositions and different geometries), in organometallic complexes. Currently, the Luminescence Department is working on the production of nanoparticles by an original method in an aqueous medium with acoustic effects, on the development of organic light-emitting devices (OLED), on the creation of effective ionizing radiation detectors, etc.

New generation organic light-emitting diodes based on luminescent beta-diketonate complexes of rare earth elements
The project is aimed at developing efficient and economical light sources based on coordination compounds of rare earth ions – europium, terbium, neodymium, samarium, with a ligand environment based on 1,3-diketones. Within the framework of the project, it is planned to conduct studies on the dependence of the efficiency of the transmission of electronic excitation energy on the structure of the ligand environment in the complex; these studies will be carried out on homologous series of complexes with minimal changes in the structure of ligands. Based on the data obtained, models of transmission and relaxation of the energy of electronic excitation will be constructed, and the main directions of modification of the ligand environment to achieve the maximum quantum yield of luminescence will be formulated. Prototypes of organic light-emitting diodes will be developed and optimized based on compounds with maximum luminescence efficiency.
