Combustion synthesis and luminescence characteristic of Eu3+- doped barium stannate nanocrystals

It is the first time that the undoped and Eu3+- doped barium stannate nanocrystals with definite morphologies are synthesized using a new combustion method. This method offers several attractive advantages such as: currency for any reagents, simple process, surprisingly short calcination time, availability of mass production and good repeatability with low cost. The characteristics of the as-synthesized nanocrystals are described with X-ray diffraction, transmission electron micrograph and luminescence spectrum.
