Modifying the Fluorescence of CdTe Quantum Dots by Silica-coated Gold Nanorods
The influence of Au nanorods coated with a silica layer on the photoluminescence (PL) of CdTe quantum dots (QDs) was investigated. The Au nanorods were prepared using a seed-mediated method. They were coated with a silica layer on the surface and CdTe QDs were connected to the surface of the silica...

| Summary: | The influence of Au nanorods coated with a silica layer on the photoluminescence (PL) of CdTe quantum dots (QDs) was investigated. The Au nanorods were prepared using a seed-mediated method. They were coated with a silica layer on the surface and CdTe QDs were connected to the surface of the silica layers. The PL spectra suggested that the quenching effect of the Au nanorods was decreased by the isolation of the silica layer. Through the time-resolved PL measurement, it was found that the PL decay of QDs became faster. The Au@SiO2-CdTe complex could poten‐ tially be used in biological sensing and thermal therapy. |
