Abstract

For the fabrication of nanoparticle containing optical fibers by melt and draw technique, nanoparticle stability at high temperatures is a requirement. We report the synthesis of quantum dots at temperatures as high as 1000 °C, compatible with fiber drawing, stabilized for the first time by a prior low temperature heating step. It is observed that quantum dots formed by this two step heating leads to a better emission stability at high powers associated with a reversible phenomenon, making these nanomaterials suitable for further technological applications.
