Abstract

Abstract: Zn1‐ x Mg x O microcrystals are produced in the 0.15 ≤ x ≤ 1 composition range by calcination of ZnO + Mg(OH)2 after hydro micro mechanical activation according to the patent WO2018065735A1. The structural properties of the samples have revealed the cohabitation of wurtzite and rock‐salt phases for x values ranging from 0.15 up to 0.6 with a clear increase of the proportion of cubic phase with x . A single cubic phase is observed in the range 0.66 ≤ x < 1. From the purity of these samples produced at very low cost, it is expected that they will be used as precursors for growth of advanced light emitters integrated into an already existing process as they exhibit exceptionally efficient (and robust with T) light emission in the ultraviolet region. Abstract : Beginning with a discussion of the scientific context that motivates the study and its aim, a description of the growth of the samples is then made, which is followed by the measurements of their physical properties in terms of structural properties and light emission efficiency. The evaluation of the materials realized and remarks conclude the paper.
