Abstract
An innovative route is reported to fabricate nano-particles in aqueous solution from oxyfluoride glass by the thermal induction and corrosion treatment in this letter. The investigations of X-ray diffraction and transmission electron microscope based on nano-particles in glass ceramics (GCs) and aqueous solution indicate that the nano-particles formed in glass matrix during the thermal induction process are released to aqueous solution and their structure, shape and luminescent properties in glass host can be kept. Owing to the designable composition of the nano-particles during glass preparation process, the method is a novel way to obtain nano-particles in aqueous solution from GCs.

[2,3,4,5] The advantages of these materials are that the rare earth (RE) ions can be incorporated selectively in the fluoride crystal phase with lower phonon energy after thermal induction and the materials remain transparent due to the nano-scale size of precipitated crystals much smaller than the wavelength of visible light
Summary
Keywords Nano-particles Á Glass ceramics Á Thermal induction and corrosion treatment The nano-particles in aqueous solution were obtained by hydrofluoric acid corrosion treatment, adjusting pH value and dispersion of surface active agent. The peaks position and half peak breadth of XRD are in concordance with those measured in GCs, which indicates that nano-particles are released from glass matrix to aqueous solution.
