CdSe/ZnS Quantum Dots
Creative Diagnostics provides CdSe/ZnS core-shell semiconductor quantum dots with
emission range from 500 nm to 650 nm. Our CdSe/ZnS quantum dots are gradient
alloyed semiconductor materials with size dependent optical/electronic properties, high
fluorescence efficiency, low toxicity and easy cell absorb. Through surface passivation
of high bandgap ZnS shell, low luminescence efficiency caused by defects and surface-
trap states can be significantly minimized. Our CdSe/ZnS quantum dots can be used in
highly sensitive cellular imaging, drug delivery and light emitting devices.
Applications:
Highly sensitive cellular imaging
Photovoltaic devices
Drug delivery
Solar cells
Light emitting devices
