摘要：Series sample were prepared with solvothermal method using ethylene- diomine as solvent, at 220 degrees C for 24h. All samples are white powder and XRD proofs that all of them are single phases. Using the Laser granularity cryoscopy(rise 2008) to measure the samples' size, and most samples' sizes are from 150nm to 200nm. SEM photo shows that the Y2O2S: Eu3+ morphologies are spherical but have some aggregation. Emission spectrum of Y2O2S:Eu3+, Mg2+, Ti4+ shows that while co-doping Mg2+, Ti(4+)ions, the strongest peak dosen't change. Prepared with high temperature solid insoluble samples compared to samples of this water-soluble luminous intensity is not high.
