Abstract
The dimensions of a crystalline matrix may be reduced for developing compact photonic devices. The goal of this work is to study the preparation of shaped microcrystals of LiLa(WO4)2:RE3+ as single crystal fibers (micro-pulling-down technique) and as powder (polymerizable complex method). The phase equilibrium relations of the Li2W2O7 - La2W2O9 pseudo system will be also investigated for …
