NOVELTY - Preparing room temperature phosphorescent material containing graphene oxide with microwave radiation comprises firstly using modified Hummers method to oxidize the graphite to obtain graphene oxide, dissolving acrylamide in water, adding graphene oxide aqueous solution and ammonium persulfate dispersed by ultrasonic wave, where the ratio of acrylamide, graphene oxide, ammonium persulfate and water is 100:0.0001-0.002:0.5-1.5:500-2000, mixing uniformly, adding in microwave chemical reactor, refluxing for 3-10 minutes under a microwave output power, cooling, precipitating the obtained product with methanol, filtering, washing the filter cake with methanol and freeze-drying to obtain room temperature phosphorescent material containing graphene oxide with long service life. USE - The method is useful for preparing room temperature phosphorescent material containing graphene oxide with microwave radiation. ADVANTAGE - The method has long phosphorescence life at room temperature; ensures that the luminescence glow reaches after 16 seconds; is simple and convenient; has non-toxic product, no pollution, no heavy metal; is halogen-free; has good water solubility and wide application prospect.
