Abstract: During the mesoporous SiO2 preparation process, Sm3+ ions are dissolved in the anhydrous ethanol solution. The ethanol solution permeates the mesoporous SiO2 then the gel is formed by sol-gel synthesis method. Such, the Sm3+ ions are absolutely introduced into the porous of the mesoporous SiO2 when the gel is dried. In this study, the mesoporous SiO2/Sm3+ composite materials were synthesized by the sol-gel synthesis method. A series of characterization means were used to evaluate the structures of the materials. The near infrared spectrum was used to evaluate the luminescent characteristics. The excitation and emission spectrum of prepared materials showed that the materials had better near infrared luminescent characteristics.
