Recently,　more　and　more　interest　has　been　focused　on　zirconia　and　its　characteristics.　In　this　paper,　aluminum　can　be　successfully　incorporated　into　nano-ZrO2　via　a　cationic　surfactant　assisted　route　in　the　earlier　preparation　procedure.　XRD,　TEM,　EDS,　Uv-vis　and　N-2　adsorption-desorption　analysis　methods　were　adopted　for　the　characterization　of　prepared　samples.　The　results　show　that　aluminum　has　been　homogeneously　incorporated　into　nano-ZrO2.　The　prepared　aluminum-doped　samples　show　a　distinctive　blue　shift　in　the　Uv-vis　spectra　compared　to　normal　nano-ZrO2.　The　distinctive　increase　of　thermal　stability　and　a　mesoporous　structure　were　observed.
