This work reports on the theoretical and experimental research of photophysical properties of hybrid nanostructures
based on gold nanoparticles (AuNp) covered by phthalocyanine (Pc) layer. We focused on the theoretical treatment of Pc
molecular absorption and luminescence properties. We found out optimal sizes for the hybrid structure core when the
maximum of Pc shell molecular absorption is achieved. Optimal core sizes for enhancement of the molecular
luminescence were also obtained. AuNp-Pc hybrid structure with average core radius of 10 nm and Pc shell thickness of
2.5 nm were experimentally synthesized. The calculation results were compared with the experimental data, so we
obtained well coincidence between each other.
