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]. This interesting phenomenon causes unique properties in DMS dots that can be explored in different technological applications, such as wavelength tunable lasers[3], solar cells[4,5], or in spintronic devices[6,7]. In this context, glass matrix-encapsulated Cd1-xMnxS NPs emerge as potential. | Nanocrystals Synthesis - f Characterization and Applications NANOCRYSTALS -SYNTHESIS characterization AND APPLICATIONS Edited by Sudheer Neralla Nanocrystals - Synthesis Characterization and Applications http 2560 Edited by Sudheer Neralla Contributors Noelio Oliveira Dantas Ernesto Soares de Freitas Neto Peter Petrik P.
