Preparation of chitosan beads by cross-linking method through electrostatic interaction with tripolyphosphate ions, combined with emulsification method using SPG membrane was studied. Next, hybridizations between green-emitting YAG:Ce3+ nanoparticles and chitosan beads, and between red-emitting Eu3+-doped apatite nanoparticles and chitosan beads were studied. Hybridizations between Eu3+-doped apatite nanoparticles and silica beads, and between YAG:Ce3+ nanoparticles and alginate beads were also studied.

采用三聚磷酸根离子静电交联法结合乳化法制备了壳聚糖微球。接下来，研究了发绿光的YAG：Ce 3+纳米颗粒与壳聚糖珠之间的杂交，以及发红光的Eu 3+掺杂的磷灰石纳米颗粒与壳聚糖珠之间的杂交。此外，还研究了Eu ~（3+）掺杂的磷灰石纳米粒子与二氧化硅微球、YAG：Ce ~（3+）纳米粒子与海藻酸盐微球的杂化作用。
