Novel transparent MgGa2O4 and Ni2+-doped MgGa2O4 ceramics
文献摘要：
In this study we fabricated,for the first time,magnesium gallate(MgGa2O4,a partially inverted spinel)transparent ceramics,both undoped and doped with 1 at％Ni.The specimens were derived from in-house prepared powder,with a crystallite size of～10 nm(by wet chemistry)and densified by pulsed electric current sintering(PECS;peak temperature 950℃for 90 min).Densification levels of 99.84％and 99.52％of theoretical density were attained for doped and undoped materials,respectively.Doping with Ni was seen to marginally improve the densification level.Quite transparent specimens were produced:the best showing transmission of～89％of the theoretical level(thickness t=0.85 mm).The absorption spectra revealed that the dopant was accumulated as Ni2+in the octahedral sites of the lattice,as occurs in single-crystal specimens.After excitation at 980 nm,the doped disks exhibited a wide fluorescence band centered at 1264 nm.
