The homopolymer PBVMA in DMF solution emitted blue fluorescence, and the copolymer PBVMA-b-PMHNS emitted orange fluorescence at about 610 nm due to the intramolecular energy transfer.
The aqueous FITC-Cys (PVim -Trp-OMe bioconjugate solution emits green light and exhibits a fluorescence emission with a maximum at 520 nm.
This dye, existing as a monomer in solution, emits a green fluorescence and can assume a dimeric configuration that emits red fluorescence in a reaction that is driven by the mitochondrial transmembrane potential.
The ZnO NP solutions emitted light under excitation with UV light (Figure 1b), with the intensity of the emitted light increasing with respect to the amount of NaOH that had been added into the solution.
However, two star polymers in DMF solution emit week red light and strong UV light at 350 400 nm, it points that energy transfer cannot occur from the carbazole to the Zn porphyrin core effectively.
Unlike the weak PL emission of PSP small molecules in a solution, PFO-PSP solutions could emit strong lights with PL quantum yields between 13 and 30%, indicating that the incorporation of the PSP into the conjugated rigid main chain could greatly restrict the rotations of the phenyl groups of the PSP units even in a solution.
Two sorts of CQDs can be obtained within the deionized water and NaOH solution, respectively, where the CQDs in water (NaOH solution) can emit blue (green) light under the UV irradiation.
At room temperature, complexes 2, 3 emit blue luminescence from 445 to 485 nm in DMSO solution, and emit green/yellow and orange luminescence from 523 to 585 nm in solid state.
Upon heating the solution will emit ammonia fumes, so do this outside or in a well-ventilated area.
The activity of photocatalyst of Sm ZnO Ag was checked for the photodegradation of thiazin-type methylene blue (MB) dye in aqueous solution using light emitting diodes/solar illumination.
