چکیده انگلیسی
In this paper, we investigated the spectroscopic properties the 1, 2, 3, 8-tetrahydrofuran, 2, 3, 8-(LD-473) dissolved in seven types of solvents with different concentrations. The absorption, emission, fluorescence and its quantum yield and Stokes shift of LD-473 were measured. The amplified spontaneous emission (ASE) spectra of LD-473 have been obtained using a transverse laser cavity configuration, where the LD-473 was pumped by laser pulses from the third harmonic of an Nd: YAG laser (355â¯nm). LD-473 in non-polar solvents exhibits dual ASEs around 445 and 470â¯nm, whereas the corresponding fluorescence spectrum shows only one peak around 437â¯nm. The peak at 470â¯nm is due to the combination of two excited molecules and the solvent between them.
