Professor Aleksander Jabłoński (born 26 February 1898 in Woskresenówka, in Imperial Russia, died 9 September 1980 in Skierniewice, Poland) was a Polish physicist and member of the Polish Academy of Sciences. During the World War I he served in the Polish I Corps in Russia. After the war he settled in Warsaw in 1918. In 1919-1920 he fought for Poland against aggression by Soviet Russia (and was consequently decorated with the Polish Cross of Valour). Jabłoński initially studied the violin at Warsaw Conservatory, under the virtuoso Stanisław Barcewicz, but later switched to science. He received a Ph.D. from the University of Warsaw in 1930, writing a thesis ''On the influence of the change of the wavelength of excitation light on the fluorescence spectra''. He then went to Friedrich-Wilhelms-Universität in Berlin, Germany for two years (1930–31) as a fellow of the Rockefeller Foundation. He worked with Peter Pringsheim at the FWU and later with Otto Stern in Hamburg. In 1934 Jabłoński returned to Poland to receive habilitation from the University of Warsaw. His thesis was ''On the influence of intermolecular interactions on the absorption and emission of light'', the subject to which he would devote the rest of his life. Jabłoński was a pioneer of molecular photophysics, creating the concept of the "luminescent centre" and his own theories of concentrational quenching and depolarization of photoluminescence. He also worked on pressure broadening of emission spectra lines and was the first to recognize the analogy between pressure broadening and molecular spectra. This led to development of the quantum-mechanical pressure broadening theory. Fluorescence is illustrated schematically with the classical Jablonski diagram, first proposed by Jabłoński in 1933〔(Nature.com )〕 to describe absorption and emission of light. ==References== * (Complete list of papers published by Professor Aleksander Jablonski ) * (A short biography of Aleksander Jabłoński ) * (Kompletna lista prac Aleksandra Jabłońskiego ) * (Aleksander Jabłoński fulltext articles in Kujawsko-Pomorska Digital Library ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aleksander Jabłoński」の詳細全文を読む スポンサード リンク
