چکیده انگلیسی
Tb-doped ZrO2 nanotube arrays were first prepared by anodizing the Zr-Tb alloys, and then Ag modified Tb-doped ZrO2 nanotube arrays were obtained by loading Ag onto the Tb-doped ZrO2 nanotube arrays through a thermal decomposition and formaldehyde reduction method. The influences of modification of Ag nanoparticles and AgNO3 concentrations (0.0001, 0.001, 0.01â¯M) on the light absorption and photoluminescence (PL) properties were determined. Results show that Ag modified samples prepared by the thermal decomposition method exhibited a significant surface plasmon resonance(SPR) effect, and that the absorption and PL emission peaks were markedly enhanced. Compared to the Tb-doped ZrO2 nanotube arrays, the PL intensity of the sample prepared using the thermal decomposition method in 0.001â¯M AgNO3 solution was enhanced by 45.8%. The samples prepared by the formaldehyde reduction method displayed excessive deposition and oversizing of Ag particles, resulting in worsening of the properties of samples.
