Abstract
The present invention relates to a method of preparing a carbon nanotube-quantum dot conjugate having a high density of quantum dots (QDs) on its surface. This method involves providing a plurality of semiconductor quantum dots and providing a thiol-functionalized carbon nanotube having a plurality of terminal thiol groups on its surface. The plurality of semiconductor quantum dots are attached to the surface of the carbon nanotube under conditions effective to yield a carbon nanotube-quantum dot conjugate having a high density of quantum dots on its surface. The present invention also relates to a carbon nanotube-quantum dot conjugate having a high density of quantum dots on its surface. The present invention further relates to a photodetector device. This device includes a substrate and a nanocomposite layer. The nanocomposite layer includes a plurality of the carbon nanotube-quantum dot conjugates previously described.
