Zusammenfassung:The invention discloses a Sr2MgSi2O7:Eu,Dy silicate system hollow luminescent sphere for luminescent ink and a preparation method thereof, belonging to the field of luminescent materials developed from functional materials. The Sr2MgSi2O7:Eu,Dy silicate system hollow luminescent sphere is prepared from the following components in parts by weight: 90 to 100 parts of Sr(NO3)2, 50 to 60 parts of Mg(NO3)2.6H2O, 0.1 to 0.2 part of Eu2O3, 0.1 to 0.2 part of Dy2O3, 2 to 4 parts of H3BO3, 14 to 16 parts of citric acid, 50 to 80 parts of a 3-(2,3-epoxypropoxy)propyltrimethoxysilane coupling agent, 50 to 100 parts of ethyl silicate, 1 to 10 parts of pollen, 100 to 200 parts of deionized water, 10 to 30 parts of absolute ethyl alcohol and 1 to 3 parts of concentrated HNO3. The preparation method comprises the following steps: by using rape pollen as a template agent, coating the rape pollen with a layer of silane coupling agent, drying the rape pollen, soaking the rape pollen in Sr-Mg-Si-Eu-Dy sol, drying the pollen coa
