▎ 摘　　要

NOVELTY - A nano-silver loaded graphene and quantum dot co-doped polymer comprises 1-3.5 parts mass nano-silver graphene, 5-20 parts mass semiconductor quantum dots, 20-74 parts mass photosensitive polymer, and 1-5 parts mass photoinitiator. USE - Nano-silver loaded graphene and quantum dot co-doped polymer is used for random laser (claimed). ADVANTAGE - The polymer can be prepared by an economical, simple and quick method using simple and easy-to-obtain raw materials, and has high light emission intensity and low threshold value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene nano-silver loaded and quantum dot co-doped polymer, which involves blending the photosensitive polymer with the photoinitiator to obtain a mixed solution, adding the semiconductor quantum dots to the mixed solution, stirring to obtain solution, adding nano-silver loaded graphene to the solution, stirring, and solidifying using UV light.
