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　x　10(-6)　to　4.0　x　10(-4)　mol　L-1.
