CoCo-LNO: LiNbO3-based core-shell nanostructures

Objectives

The academics of core-shell structures based on LiNbO3 alone is envisaged by simply mixing nanocrystals of different sizes, i.e. 20 nm particles doped with Yb3+, for example, with larger cores doped with Er3+ (30-40 nm). The synthesis of these nanocrystals has been mastered to date, but aging at high temperature in a mixture maintained under magnetic agitation (instrumented autoclave) has never been studied. Non-linear optical properties and up-conversion will then be greatly enhanced and quantified.
