Summary: This study examines the effects of solvents with different polarities on the electronic absorption and fluorescence spectra of PBBO, and evaluates the dipole moments of the excited and ground states. Results show that the dipole moments of the excited state are larger than those of the ground state. Additionally, the study observes the impact of silver nanoparticles on the emission spectrum of PBBO. Energy transfer between PBBO and laser dyes will be further investigated, along with the calculation of absorption spectra, energy gap, bond length, and IR spectrum using density function theory.

Summary: The effect of replacing guanosines with inosines in the stabilizing strands of NIR emissive DNA-Ag16NC was studied. The spectroscopic behavior of the inosine mutants varied depending on the position, with a shorter fluorescence decay time when guanosine at position 7 was replaced and a longer decay time when inosine was at position 9. The observed changes could be explained by the structural information obtained from single crystal X-ray diffraction measurements.

Summary: A microcrystalline Eu(III) complex was synthesized using dehydroabietic acid (DDA) and 1,10-phenanthroline (Phen) through a one-step precipitation method. The complex showed enhanced absolute quantum yield and decreased full width at half maxima compared to the complex with only Phen. The introduction of DDA suppressed the C-H bending vibrations of Phen and decreased the reorganization energy of the complex. The complex exhibited effective sensing performance for gallic acid in ethanol solution.

Summary: In this study, white light emission (WLE) was observed from imperfect H-aggregates of co-facially pi-pi stacked humin-like structures in carbon dots (CDs) synthesized through hydrothermal treatment of a single precursor, dextrose. The H-aggregates exhibited a broad range of excitation-dependent emission spectra with color coordinates close to pure white light. The findings suggest the potential use of CDs as a cutting-edge fluorescent material for creating aggregate-induced white light emission.
