The one-pot synthesis of core/shell/shell CdTe/CdSe/ZnSe quantum dots in aqueous media for in vivo deep tissue imaging

Water soluble, near infrared emitting type II/type I CdTe/CdSe/ZnSe quantum dots were synthesized in a simple one-pot procedure. The emission wavelength could be tuned from 530 nm (original CdTe core) to 670 nm and the particle size was determined by TEM measurement. The resulting quantum dots were used in subcutaneous deep tissue monitoring.
