The Research of Solvothermal Method Preparation of Y₂O₂S:Eu³⁺_0.06, Mg ²⁺_0.04,Ti⁴⁺_0.01 Water-Soluble Red Afterglow Materials

Abstract:

Series sample were prepared with solvothermal method using ethylene-diomine as solvent, at 220°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⁺,M g ²⁺,Ti⁴⁺ shows that while co-doping M g ²⁺,Ti⁴⁺ions , the strongest peak dosent change . Prepared with high temperature solid insoluble samples compared to samples of this water-soluble luminous intensity is not high.
