The pressure response of the ultraviolet photoluminescence of ZnO nanocrystallites and MgZnO nanoalloy of composition 15% Mg:85% Zn of the wurtzite structure was studied. The authors found that up to the pressure coefficients of ZnO and MgZnO are 23.6 and , respectively. The pressure coefficient of the ZnO nanocrystallites is similar to that reported elsewhere for bulk ZnO material. The higher value found for MgZnO is discussed in terms of the orbitals of the alloy constituents and their compliance to stress. Additionally, the volume deformation potential was derived from the experimental results.
