| 摘 要： | 以Y2O3,Yb2O3,Er2O3为原料,利用燃烧法分别制备了Y2O3:Er3 和Y2O3:(Yb3 ,Er3 )两种纳米材料和相应的体材料Y2O3:(Yb3 ,Er3 ).用发射波长为978 nm的半导体激光器和日立F-4500荧光分析仪测量了它们的上转换发光,得到纳米材料Y2O3:Er3 的上转换发光主要为绿色上转换发射而纳米材料Y2O3:(Yb3 ,Er3 )主要为红色上转换发射,而后者与激活离子掺杂浓度相同的体材料Y2O3:(Yb3 ,Er3 )的上转换发射相比较,体材料以绿色上转换发射为主、红色上转换发射很弱.

| Abstract: | Two nanomaterials Y_2O_3: Er~(3 ) and Y_2O_3:(Yb~(3 ),Er~(3 )) were prepared by combustion on the basis of reagents Y_2O_3,Yb_2O_3 and Er_2O_3.The corresponding host Y_2O_3:(Yb~(3 ),Er~(3 )) was obtained by increasing calcination temperature.Upconversion emission was obtained under 978 nm LD excitation.Comparing nanopowder oxide Y_2O_3:Er~(3 ) with nanometer materials Y_2O_3:(Yb~(3 ),Er~(3 )) with respect to upconversion spectra,the upconversion emission of the former mainly was green upconversion and that of the latter mainly red light.However,the upconversion emission of nanopowder Y_2O_3:(Yb~(3 ),Er~(3 )) was different from that of its corresponding host,with main red upconversion emission for the former but main green upconversion emission on the latter. |
