Organic compounds have great potential in light amplification and modulation applications in the field of a sensor (lab-on-chip, gas sensor) or communication (light source, light modulators). But it is still on the way of commercialisation due to the low stability or efficiency of the organic compounds, or size of the structure. Introduction of metal nanoparticles or nanostructures in organic material is one of the possible solutions for previously mentioned issues. Surface plasmon resonance of metal nanostructures improves light emission and modulation efficiency of organic compounds and can increase the sensitivity of the system. This fundamental project is devoted to develop and investigate novel organic compound/metal nanoparticle or nanostructure systems for enhancing light amplification and modulation properties in a red and infrared spectral region. The project will last for three years, during which metal nanoparticle synthesis and metal nanostructuring will be carried out in the first year. The most appropriate nanoparticles/nanostructures will be selected for the preparation of organic compound/nanoparticle systems. The systems will be evaluated from the optical properties measurements. The best of the systems will be used to measure light amplification or modulation properties. The gained knowledge about the interaction between the metal nanoparticle/nanostructures and organic compound will be one of the results of the project.
