Freestanding Ge/GeO_𝟐 Core-Shell Nanocrystals with Varying Sizes and Shell Thicknesses: Microstructure and Photoluminescence Studies

Figure 2

XRD patterns of the freestanding Ge/GeO₂ core-shell NCs milled for different time duration. Intensity of the GeO₂(101) peak increases systematically with increasing milling time.
