Abstract

Based on microscopic (exciton) theory of optical properties of symmetrically perturbed ultrathin 
molecular films, the absorption, reflection and transparency indices were formulated and presented in 
the function of frequencies of external electromagnetic field in near IR region. 
It has been showed that all optical properties depend on the position of the crystal plane with regard 
on boundary planes of the film. We have determined and analyzed optical properties relations for the 
whole film structure based on the consideration for multiple reflection, absorption and transparency 
in those multilayered structure. 
The three-layered dielectric nanofilms with different boundary conditions on surfaces were analyzed 
and some discrete resonant absorption lines were obtained. Their number, position and distribution 
depend on the boundary parameter values, i.e. on the type and the technological process of their 
preparation/fabrication. Practically monochromatic absorption may occur. Unlike the corresponding
balk-samples which are total absorbers throughout the near IR region, in ultrathin films will appear 
selective and discrete reflection and transparency too. 
These results could give a great contribution in optical engineering of nanostructures, especially in 
technology of designing of new electronic and photonic equipment, and for nanoparticles construction 
for drug carrier/delivery in nanomedicine
