AgInS2/ZnS QD, ROTI®nanoMETIC Lambda max. 640 ±20 nm, 10 mg, glass

ROTI^®nanoMETICQuantum dots (QD) are fluorescent nanoparticles of certain semiconducting materials, whose electronic properties closely depend on the size of the particles. The fluorescence wavelength shifts towards red for larger particles, and to blue for the smaller ones. This allows coverage of the complete visible colour spectrum with quantum dots of different sizes and yet the same material. The possibility to control the size of the particles during their manufacturing, allows to precisely adjust their electronic and fluorescent properties. The inorganic nature of quantum dots makes them far more stable than organic fluorescent dyes.

AgInS₂/ZnS, hydrophobic, heavy-metal-freeAgInS₂/ZnS (core/shell) are non-toxic heavy metal free (no Cd, Se, Hg and Cu) luminescent quantum dots coated with hydrophobic ligands. These quantum dots are easily dispersible in hexane, cyclohexane, toluene, chloroform, THF, pyridine and similar solvents but not in water, alcohols and ethers.The products are supplied as powder in 2 ml vials with septum. Thus, the quantum dots can be dispersed directly in the vial with the desired solvent.
