Electrogenerated chemiluminescence emission from cadmium germanate nanoparticles

The ECL phenomenon of nano Cd2Ge2O6, both amorphous and crystallized, is described in this paper. This is the first report on the ECL of semiconductor nanocrystals involving three elements and also the first paper dealing with the amorphous nanomaterials, which shed some light on the exploration of new ECL nanomaterials. The ECL mechanism could be ascribed to the cadmium-rich surface state of amorphous Cd2Ge2O6. The ECL intensity linearly increased along with the square of the H2O2 concentration. Therefore, it was employed to detect hydrogen peroxide, and the linear range was 5.0 × 10−6 to 4.0 × 10−4 mol L−1.
