附注sno2/zns one-dimensional core/shell nanowires have been synthesized by two-step growth process. phase and structural analyses reveal that the core has a single crystalline phase, whereas the shell has polycrystalline phase covering the surface of the core. the optical properties of sno2 nanowires change as a function of the zns shell thickness. the increase in photoluminescence intensity at the stage when the shell is very thin is attributed to the surface modification by the zns shell. when the shell gets thicker the intensity of the photoluminescence decreases because a type-ii band alignment is formed between the core and shell. the changes are also detected in the raman spectra: new lines caused by surface optical phonons emerge shell is very thin, and their intensities decrease with the increase of the shell thickness.
