Description
CdSe/ZnS QD, ROTI®nanoMETIC Lambda max. 550 ±5 nm, UN-Nr. 1759
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.
CdSe/ZnS, hydrophobicThe CdSe/ZnS (core/shell) quantum dots are highly luminescent semiconductor nanocrystals coated with hydrophobic organic ligands consisting mainly of trioctylphosphine oxide. These quantum dots are easily dispersible in hexane, cyclohexane, toluene, chloroform, THF, pyridine and similar solvents but not in water, alcohols and ethers. The thickness of the ZnS shell is approx. 0.6 nm. The products are supplied as dry powders in 2 ml vials with septum. Thus, the quantum dots can be dispersed directly in the vial with the desired solvent.

Questions about CdSe/ZnS QD, ROTI®nanoMETIC Lambda max. 550 ±5 nm, 5 mg, glass
What is this article?
CdSe/ZnS QD, ROTI®nanoMETIC Lambda max. 550 ±5 nm, 5 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Nanomaterials & quantum dots, inside Inorganic chemicals, in Lab chemicals.
A nanomaterial is defined by a particle size that changes how it behaves. A quantum dot's optical emission depends on that size. The stated diameter, the surface coating and the concentration are the specification. The bulk powder of the same composition is not this product.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Nanomaterials & quantum dots. The catalogue is Lab chemicals.
Shelves beside this one are Inorganic salts and Metals, elements & oxides.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
