Mechanico-chemical interactions of single-walled carbon nanotubes (SWNTs) with zinc oxide (ZnO) were investigated by surface-enhanced Raman scattering (SERS) and photoluminescence (PL). We show that SWNTs dispersed into a ZnO host matrix and compressed non-hydrostatically at 0.58 GPa forms a new organic/inorganic hybrid material. The typical PL emission of nanometric size ZnO particles changes gradually with the increase of the SWNTs concentration in the SWNTs/ZnO hybrid material. As a result of the mechanico-chemical interaction with SWNTs, the '' green '' band at 2.8 eV, attributed to oxygen vacancies of ZnO nanoparticles, decreases continuously until its complete disappearance.
