摘　　要：利用减压抽滤法,使Er(NO_3)_3·5H_2O和Na OH溶液在氧化铝模板(AAO)纳米孔中反应,并经高温煅烧,制备出高规则和高密度的Er_2O_3纳米管阵列。通过SEM、TEM、SAED、XRD和EDS等对产物的形貌、结构、组成和含量进行表征。结果表明,Er_2O_3纳米管为非晶型结构;元素组成的原子百分比Er∶O为7.61∶69.11,重量百分比为42.33∶36.78;经磁性能分析,发现Er_2O_3纳米管具有超顺磁性。Highly ordered and high-density Er2O3 nanotube arrays were prepared in AAO nanoporous template with the reaction of Er（ NO3）3·5 H2 O and Na OH solution by subatmospheric filtering and calcination at high temperature. The products were investigated about the morphology,structure,composition and content by SEM,TEM,SAED,XRD and EDS. The results indicate that the Er2O3 nanotube is amorphousthe atomic percentage of Er∶ O is 7. 61 ∶ 69. 11,and the weight percentage 42. 33 ∶ 36. 78. The analysis of magnetic property reveals that the Er2O3 nanotube arrays are superparamagnetic.
