Submicrometer hollow spheres of CdSare produced here (see Figure) in a one-pot in-situ source–template–interface reaction (ISTIR)—thus named because CS2 plays both the role of sulfur source and template and the main reaction region is at the CS2–water interface. Examination of the photoluminescence spectrum of these spheres indicates quantum confinement.
