Latest Publication from Quantum Dot Lab, JNCASR

Our new review article in ACS Applied Nano Materials, published by the American Chemical Society, explores the evolution of colloidal plasmonic heterostructures—from noble metals to semiconductor plasmonic materials, and from traditional II-VI to modern halide perovskites.

While several review articles exist on this topic, our paper uniquely addresses two key aspects for the first time:

  • Plasmonic halide perovskite heterostructures: Despite the presence of Au, why do most of them remain non-plasmonic?
  • Synthesis and light-matter interaction: Focusing on semiconductor plasmonic heterostructures, including metal oxides and chalcogenides.

Authored by: Saptarshi Chakraborty, Subham Das, Gauttam Dash, and Prof. Ranjani Viswanatha.
