Syllabus


  • Introduction of nanoscale materials: density of states, quantum confinement effect
    Moores law, confinement effect on the physical and chemical properties of metals, semiconductors, core/shell nanostructures, quantum wells, etc.

  • Synthesis of metal nanoparticles: (Au, Ag, Cu) via different routes such as colloidal, hydrothermal, microwave, micro-emulsion, etc. In addition, synthesis of different shaped (triangle, prism, cubes) nanoparticles will be discussed. Optical properties, surface Plasmon resonance, and their shape dependence.

  • Synthesis of semiconductor nanoparticles: CdSe, CdS, PbSe, ZnS, ZnOstrategy to make monodispersed nanoparticles, confinement effect on the optical properties, surface modifications, etc.

  • Magnetic nanomaterials: synthesis, hysteresis loop, coercively, super paramagnetism, single domain, effect of particle size.

  • Techniques: electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM), UV-Vis, fluorescence spectroscopy, dynamic light scattering and Zeta potential methods and their use in the characterization of nanomaterials.

  • Catalytic activity of nanoscale materials: Example: Au, Pd, Cu, TiO2.

  • Self-assembled monolayers: preparation, characterization, application in pattern creation (lithography) microcontact printing, nano imprint, colloidal lithograohy, nanodots.

  • Layer-by-layer method for the fabrication in 2-dimentional and 3-dimentional surfaces, hollow nanoparticles and their application in drug delivery

  • Nanocomposites: preparation, characterization and applications.

  • Applications of above nanomaterials in biology, medicine, etc

  • Optical spectroscopy of single nanoparticle: The need for single particle studies and the involved challenges.Single nanoparticle absorption: Direct (attenuation based) and Indirect (Photothermal Imaging and Ground state depletion) methods.

  • Single nanoparticle photoluminescence: Detection methods: epifluorescence and confocal imaging, Case studies to understand dependence of incident intensity and acquisition time, quantum confined stark effect, spectral jitter, spectral diffusion, PL intermittency or blinking and mechanism, kinetics of blinking and various models, Suppression of blinking.
