The effect of solvent used for fabrication on the room-temperature phosphorescence of B2 O3/SiO2 nanoparticles has been studied. The phosphorescence spectra of B2 O3/SiO2 nanoparticles are featured with two peaks in the visible region. The emission band centered at 520-540 nm is found to originate from B2 O3 while that centered at 470-480 nm originates from SiO2. However, B2 O3/SiO2 nanoparticles fabricated by using different solvent will make the relative intensity of the two phosphorescence peaks dif-ferent. The solvent in favor of dispersing boric acid into the TEOS will enhance the relative intensity of phosphorescence originated from B2 O3 .%本文通过对比不同溶剂制备的B2 O3/SiO2纳米复合材料室温磷光光谱，并结合FTIR及XRD的表征结果，研究溶剂对该材料磷光性能的影响。结果表明，不管用何种溶剂制备B2 O3/SiO2室温磷光材料，均存在两个磷光发射峰，一个是位于520-540nm之间，该发光可能是与氧化硼有关的二氧化硅杂质缺陷发光，另一个位于470-780nm处，该磷光峰推测是二氧化硅的结构缺陷发光。但是在制备过程中溶剂将影响氧化硼在二氧化硅结构中的掺杂，进而影响其发光中心的相对发光强度。
