Abstract
In this work, 1-(4-methylsulfonyl phenyl)-3-(4-N, N dimethyl amino phenyl)-2-propen-1-one (MSPPP) chalcone was synthesized and examined as optical materials. The absorption and fluorescence characteristics of MSPPP chalcone were recorded in ten different solvents. The influence of functional groups (FG) and solvents on their photophysical properties were investigated. These include absorption, fluorescence, stokes shift, and amplified spontaneous emission (ASE). The absorption spectra of MSPPP showed a wavelength band in the range 404 - 427 nm, whereas the fluorescence spectra exhibited a band at 473 - 533 nm. The FGs and solvents had an adorable effect on the optical properties of the synthesized materials. ASE was observed under pump pulse laser excitation, and the wavelengths were attuned from 511 to 548 nm.
