| 摘 要： | 在不加任何表面活性剂的条件下,通过水热法直接合成了LaPO4:Eu3+纳米棒,并采用溶胶-凝胶法在其表面修饰了一层SiO2,得到了LaPO4:Eu3+@SiO2纳米棒.XRD分析表明,样品包覆前后均属于单斜晶系的独居石型的LaPO4.FTIR分析表明,LaPO4:Eu3+粒子与SiO2是以化学键的形式结合在一起.由TE...

| Abstract: | LaPO_4:Eu~(3+)luminescence nanorods were prepared via a hydrothermal method without any surfactants, then an uniform SiO_2 layer was coated on the surface of LaPO_4:Eu~(3+)nanorods by sol-gel method.At lasts LaPO_4:Eu~(3+)@ SiO_2 core-shell structural luminescence nanorods were achieved.XRD patterns show that the uncoated and coated samples are all monclinic LaPO_4 crystals.FTIR spectra indicate that LaPO_4:Eu~(3+)is linked with SiO_2 by chemical bond.TEM images reveal that the LaPO_4:Eu~(3+)samples are one... |
