Analysis
This paper presents a novel synthesis method for producing quasi-2D klockmannite copper selenide nanocrystals, a material with interesting semiconducting and metallic properties. The study focuses on controlling the shape and size of the nanocrystals and investigating their optical and photophysical properties, particularly in the near-infrared (NIR) region. The use of computational modeling (CSDDA) to understand the optical anisotropy and the exploration of ultrafast photophysical behavior are key contributions. The findings highlight the importance of crystal anisotropy in determining the material's nanoscale properties, which is relevant for applications in optoelectronics and plasmonics.
