Nano-sized oxide phosphor has been actively investigated as transparent phosphors for use in solar energy converters [1], field emission applications [2] and bio-detectors [3]. In particular, oxide nanoscrolls, which is well-known as a one-dimensional (1D) materials prepared by rolling up the nanosheets, have been investigated because it is expected to exhibit unique and functional properties by structural distortion caused as a result of transformation from a nanosheet to a nanoscroll [4]. Some of the nanosheets raise the spontaneous transformation into nanoscrolls after exfoliation due to the difference of stress with asymmetric structure of the top and bottom [5]. Organization of 1D nanomaterials has attracted much attention because rational assembly of 1D building blocks into well-organized higher dimensional structures is extremely useful for the fabrication of nanodevises and open up many unique areas of nanoscience [6-7]. Up to now, organization control of nanosized 1D oxide has been succeeded by various methods, including Langmuir-Blodgett (LB) technique [8], and template-based method [9]. These methods require organic substance. However, the adsorbed organic substance on the surface of nano-sized 1D oxide and heat or UV treatments, removing the organic substance, result in the reduction of the opto-electric properties of these oxides. Therefore, new 1D materials synthesized without organic solvent is required in order to efficiently use the nanoscrolls in optical and opto-electric devices. In our previous work, we have obtained organic-free HLn(MoO4)2 (Ln = rare earth metals) nanoscroll by the H+ exchanging of alkali rare earth molybdate ALn(MoO4)2 (A = alkali metals) using dilute nitric acid solution (0.01 M) for the first time [10]. In this study, we have found that HLn(MoO4)2 formed nanobundle structure assembled some nanoscrolls by a TEM observation. The detail of the nanobundle morphology will be given a presentation on.
