It is a pleasure and an honor to comment on this outstanding book, Spectroscopic Ellipsometry: Principles and Applications by Dr H. Fujiwara. It is a tutorial introduction, yet offers considerable depth into advanced topics such as generalized ellipsometry and advanced dispersion and oscillator models for analysis of complex materials systems. Each chapter is extremely well referenced, with over 400 literature citations in total, providing the reader rapid access to considerable published literature from fundamentals to recent advances.

ZnO films were deposited on glass substrates by magnetron RF-sputtering. An accurate determination of the optical constants of these films is extremely important prior to its application in optical devices and spectroscopic ellipsometry provides a reasonably accurate method for the determination of optical constants of thin films.

Cd1-xMnxS nanoparticles (NPs) with size quantum confinement belong to the diluted magnetic semiconductor (DMS) quantum dot (QD) class of materials that has been widely studied in the last few years. The study of quasi-zero-dimensional Diluted Magnetic Semiconductors (DMS), such as Cd1-xMnxS Quantum Dots (QDs), is strongly motivated due to the localization of magnetic ions in the same places as the free-like electron and hole carriers occurring in these nanomaterials [1,2].
