“…Based on these considerations, an alternative way besides the classical heat-treatment of the pristine glass for the manufacture of glass containing rare-earth doped NC of a desired composition is based on the incorporation of previously prepared NC with suitable properties in the glass matrix. Despite such methodology is a great challenge, several chemical and physical methodologies for NC synthesis are available and are given access to a complete control of the NC composition and average size [6][7][8][9][10] . In this sense, a homogeneous distribution of these NC in complementary glass phase should open opportunities for the design of completely new composite materials, paving the way for innovative applications in electronics and photonics.…”

A direct-doping method was tested to design new composite-glasses by incorporating lanthanum niobate nanocrystals (NC) in tellurite glasses. NC powder were grinding with glass powder before heating-quenching, with the main investigation approached of best parameters for NC suitable homogenization but limited dissolution. Thermal analysis signalizes that prior heat-treatment of NC promotes higher transparency and limits NC dissolution. These materials with visually detectable NC aggregates exhibited glass transition temperatures close to the starting glass. LaNbO 4 phase was hardly detected by X-ray diffraction because of the low weight ratio and partial dissolution but the monoclinic polymorph could be identified for lower time. UV-visible-NIR transmission spectra also related progressive lower transparency with light scattering of NC aggregates. Photoluminescence suggest that lower times allowed to ensure the NC environment with lower crystallinity around Eu 3+ -ions in final composite-glass. These results pave the way for designing new materials containing NC not achievable by conventional nucleation-growth methods.
