This manuscript includes some photophysical parameters and some optical properties such as absorption and emission spectra of the (E, E)- 2,5-bis (3,4-dimethoxystyryl) pyrazine (BDP) by applying sol-gel and copolymer matrices. The BDP molecular structure is incorporated in sol-gel matrix and copolymer of methyl methacrylate (MMA) and 2-hydroxy metylmethacrylate (HEMA). In case of sol-gel matrix, the BDP molecular structure has higher quantum yield in addition to photostability maxima. The laser behavior of this molecular structure containing sol-gel matrix is good senior compared to copolymer one via using diode laser (450nm) as pumping laser of power 160 mW. Also, the fluorescence profile of the BDP molecular structure is sensitized via using cadmium sulphide (CdS) quantum dots (QDs) by applying sol-gel host. The optimized structure of the BDP molecule is obtained via applying B3LYP/6-31G(d) level of theory. The electronic absorption and emission spectra of the BDP molecular structure in ethanol solvent, were calculated using time dependent density functional theory (TDDFT) at CAM-B3LYP /6-31G++(d, p) level. The obtained theoretical results were compared to experimental ones.

“…Via utilizing Fig. 1 , the fluorescence quantum yield (ϕ f ) [ 34 , 35 ], oscillator strength ( ), transition dipole moment from ground to excited state (μ 12 ) [ 36 , 37 ], and radiative decay rate constant (K r ) [ 38 ] for the studied molecule by applying sol–gel and copolymer matrices are estimated and presented in Table 1 . The ϕ f value of the studied molecule by applying sol–gel matrix is high in contrast to copolymer matrix as listed in Table 1 , owing to high mobility of the BDP molecules in sol–gel compared to copolymer host.…”
