The article explores the influence of plasma energy of ytterbium nanoparticles on the fluorescent and absorption characteristics of the porphyrin molecules (Ethioporphyrin) in methylcellulose films. There has been ascertained the presence of plasmon energy transfer in the porphyrin-cluster system of the ytterbium nanoparticle at the wavelengths of fluorescence registration. The values of the increase in percentage proportion were defined. It was demonstrated that with the clusters concentration increasing the optical density of porphyrin molecules and fluorescence intensity increases.
The presence of plasmon resonance in the region of 375 nm for ytterbium nanoparticles obtained by laser ablation in the
stabilizer of AOT in heptane is established in the work. The dimensions of the ytterbium nanoparticles are determined by
the dynamic scattering method. Raman spectra and absorption spectra were measured in the IR region. Characteristic
vibration frequencies for ytterbium nanoparticles and scattering bands for a pure ytterbium metal surface are determined.
