The solvent effect on nanomaterials composed of liquid crystals and nanoparticles: uv-vis absorbance and fluorescence spectra
Abstract: We have been studied to determine solvent effect to interactions between 4-Ethoxybenzoic acid (4EOBA), 4-Pentylbenzoic acid (4PentBA), and 4-Pentylphenyl 4-Methylbenzoate (4PP4MetB) liquid crystals and CdS, CdSe with ZnS nanoparticles in DMSO, methanol, and toluene. For this, the absorbance and fluorescence spectra of the LC compounds in the solvent and the materials consisting of different nanoparticles were investigated. Absorbance and fluorescence electronic transitions are interpreted. The fluorescence of liquid crystals has been investigated in the shifts between wavelengths of the fluorescence of nanomaterials. It can be said that it has occurred blue shift at the maximum fluorescence wavelengths of the 4EOBA-CdS-DMSO and 4EOBA-CdSe-DMSO compared to 4EOBA-DMSO. On the other hand, we can say that in the 4EOBA-ZnS-DMSO solution occurs red shift in the fluorescence band, while the peaks seen in the fluorescence band can occur in result of interaction of liquid crystals and nanoparticles.
