Capping ZnO nanoparticles (similar to 10 nm size) with different organic molecules produces an alteration of their electronic configuration that depends on the particular molecule, as evidenced by photoluminescence and X-ray absorption spectroscopies and altering their magnetic properties that varies from diamagnetic to ferromagnetic-like behavior.engjournal articlehttp://dx.doi.org/10.1021/nl070198mhttp://pubs.acs.orgopen access538.9Quantum DotsDoped ZnOFerromagnetismSemiconductorsTemperatureFilmsNanocrystalsLuminescenceMonolayersFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
