What is it about?
We used a quasi-static technique to evaluate the local field enhancement factor (LFEF), absorption, and extinction cross-sections of spherical, cylindrical, oblate, and prolate core-shell nanocomposites. Spherical nano shell is characterized by the highest LFEF than cylindrical and spheroidal core-shell of the same size and compositions. When compared, even the smallest value of LFEF of spherical core-shell is 11.42 and 10.09 times larger than the biggest values of oblate and prolate core-shells, respectively.

Why is it important?
LFEF, absorption, and extinction cross-section of spherical and cylindrical core-shell nanocomposites possess two peaks, whereas oblate and prolate spheroids show three observable peaks. Moreover, prolate core-shell spheroid shows greater tunability and larger intensity of LFEF than its corresponding oblate structure. Such nanocomposites are promising for applications in optical sensing, bio-sensing and electronic devices. Especially, gold coated core-shell spheroids have good potential application in multi-channel sensing.
Perspectives
I think the scientific aim of this study is precise. This research question supported what is known in this field and what is the reason for this study. The figures' curves are explicitly specified with different colors and types to enhance the readers' understanding. The study methods are valid and trustworthy. Besides, the results support the findings. Given the current interest in CdSe@Au Core-Shell Nanocomposites, the community will welcome this result.
