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. And Y2O2S : Eu3+ has a better a anti-decay property compared with Rhodamine B. The Cell toxicity test (MTT) shows that when concentration range in 20-80mg/ml, the cytotoxicity of sample is relatively small,but as a good bio-marker materials in tumors' diagnosis, its toxicity is still high.
