Optical properties of Nd3+ and Yb3+ -doped metal iodates (AgM(IO3)4): transparent host matrices for mid-IR lasers and nonlinear materials

Résumé

Nine new isomorphic iodate compounds NaM(IO3)4 with M ¼ Y, Nd, Gd and AgM0(IO3)4 with M0 ¼ Y, La, Nd, Eu, Gd, Bi have been synthesized either by evaporation of concentrated nitric acid solution or by hydrothermal synthesis. They crystallize in the monoclinic acentric Cc space group. Typical unit cell parameters for AgY(IO3)4 are a ¼ 31.277(3) °A, b ¼ 5.547(1) °A, c ¼ 12.556(2) °A, b ¼ 91.11(2) , V ¼ 2178.0(6) °A3 and Z ¼ 8. Crystal structures have been solved on single crystals for NaY(IO3)4, AgY(IO3)4, AgLa(IO3)4, AgGd(IO3)4 and AgBi(IO3)4 and on powder for NaNd(IO3)4, NaGd(IO3)4, AgEu(IO3)4 and AgGd(IO3)4. They are thermally stable up to 550 C for NaY(IO3)4, 430 C for AgY(IO3)4, 500 C for AgLa(IO3)4 and 490 C for AgBi(IO3)4. The crystal structure reveals a two-dimensional layered network. The sheets are connected together by I/O interactions. All these metal iodates generate second harmonics and are transparent up to 12µm. So they are interesting as potential laser matrices in the mid and beginning of the far-infrared. The properties of Nd3+ and Yb3+-doped AgGd(IO3)4 and of Nd3+-doped AgLa(IO3)4 have been studied.
