Scientists enhance localized surface plasmon resonance through oxide particle superlattices

A research group led by Prof. Yang Liangbao from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has enhanced localized surface plasmon resonance (LSPR) by studying Cu₂O₁₋ₓ superlattices with oxygen vacancies, providing new insights into vacancy doping in semiconductors and LSPR induction in metal oxide nanoparticles. The findings are published in Nano Letters.
