Twofold advantage of gas bubbling for the advanced solvothermal preparation of efficient YAG:Ce nanophosphors
With the goal of controlling the oxidation state of cerium ions in Ce-doped Y 3 Al 5 O 12 nanocrystals (YAG:Ce), different gases (Ar/H 2 , O 2 , Ar) were bubbled inside the solution of precursors and solvent prior to the solvothermal synthesis. As assessed by X-ray absorption spectroscopy, this prot...

oxidation. In addition, gas bubbling strongly influences the size and crystal quality of YAG:Ce nanocrystals, as evidenced by X-ray diffraction and transmission electron microscopy. Indeed, the presence of bubbles in the precursor solution induces heterogeneous nucleation, leading to an earlier nucleation step. This favors the growth and the high crystallinity of YAG:Ce nanocrystals leading to record iQY at around 52% for 60 nm sized nanocrystals and 66% for those of 200 nm.
Gas bubbles modify the nucleation, crystallinity and Ce oxidation state of YAG nanocrystals: towards very high photoluminescence yields. |
