This paper was devoted to the construction of a magnetic-luminescence nanocomposite for oxygen sensing application, where superparamagnetic Fe3O4 and silica molecular sieve MCM-41 were chosen as the inner core and the outer shell, respectively. A Ru(II) complex was grafted into MCM-41 shell through a coupling ligand(More)
Two site-specific nanocomposite samples were designed and prepared for nitrite sensing. A core-shell structure was applied in them, using Fe3O4 nanoparticles as core, silica molecular sieve MCM-41 as shell and two rhodamine derivatives as chemosensor, respectively. These two composite samples and their core-shell structure were investigated by electron(More)
