Three distinct shapes such as nanotubes  nanospheres and nanoflakes formed in the products by adjusting the pH value of reacting solution. Powder X-ray diffraction analyses indicate that all the three nanostructures are pure cubic phase  while electron microscopy measurements confirm the formation of different morphologies. These nanostructures exhibit strong visible upconversion luminescence under the excitation of a 978-nm diode laser. In Yb3+- and Er3+- codoped Y2O3 nanocrystals  the relative intensity of green emission became stronger as the size and morphology of sample changed from tubes to flakes. 2006 Elsevier B.V.
