The disclosure provides a forming method of a halogen-free flame-retardant material. The method includes the followings. A twin-screw extruder including a first zone and a second zone is used. A mixture in the first zone is mixed, melted and heated to form a molten mixture. The mixture includes a halogen-free flame retardant, a wear-resistant modifier, a thermoplastic elastomer, and an antioxidant. In addition, a silane-modified nano-silica aqueous suspension is introduced into the second zone to mix the silane-modified nano-silica aqueous suspension with the molten mixture from the first zone. The first zone and the second zone are continuously connected regions.

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.
