We have developed a novel modulated photoluminescence sensor based on CdTe QDs@silica nanobeads. The PL intensity of CdTe QDs@silica nanobeads were changed significantly when Fe3+ was reduced to Fe2+ by ascorbic acid. When H2O2 was introduced to oxidize Fe2+ to Fe3+, the PL intensity of CdTe QDs@silica nanobeads can be recovered. The sensor can be used to determine ascorbic acid in tablet samples.
