A polymeric quenchant. The polymeric quenchant comprises an inorganic nanoparticle, a water-soluble polymer, and water, wherein a weight ratio of the inorganic nanoparticle, water-soluble polymer and water is about 0.05-5:1-5:100. The cooling rate of steel during a quenching process can be adjusted by regulating the components and ratios of the adjusted by regulating the components and ratios of the polymeric quenchant to achieve desirable steel properties.

Method for quenching steel

The invention provides a preparation method of ZnCdA quantum dot capable of emitting white light, in which A is S or SSe; 0&#x3c;x&#x3c;1 and 0&#x3c;y&#x3c;1. The method includes preparing a sulfur-containing organic solution; mixing a zinc-containing precursor and a cadmium-containing precursor with an organic acid, and dissolving them in a co-solvent to obtain a homogeneous solution; and mixing sulfur-containing organic solution with the homogeneous solution to produce ZnCdA quantum dot.
