A Note on Particle Size

Cadmium selenide quantum dots are specified by emission wavelength (490–610 nm, tunable), not by a standardized core particle size or mesh/sieve grading — core size is not published by the supplier and is not a meaningful spec for this product. Emission wavelength and purity (see table above) are the primary ordering specifications.

Information Required for Quotation
