The undoped and the Nd(3+):KBaGd(WO(4))(3) crystals were grown by the top seeded solution growth (TSSG) method from a flux of K(2)W(2)O(7). The structure of the pure crystal was determined by the single-crystal X-ray diffraction method. It crystallizes in the monoclinic symmetry with space group C2/c. In the structure, K(+) and Ba(2+) ions share the same 8f site with occupancy of 0.464 and 0.536, respectively. The investigation of spectral properties of Nd(3+):KBaGd(WO(4))(3) crystal indicates that it exhibits broad absorption and emission bands, which are attributed to locally disordered environments around the Nd(3+) centers. The broad absorption band is suitable for diode laser pumping.
未掺杂和 Nd(3+):KBaGd(WO(4))(3) 晶体是通过顶部籽晶溶液生长 (TSSG) 方法从 K(2)W(2)O(7) 熔剂中生长的。纯晶体的结构通过单晶 X 射线衍射法确定。它在单斜对称空间群 C2/c 中结晶。在结构中，K(+)和 Ba(2+)离子分别占据 0.464 和 0.536 的相同 8f 位。对 Nd(3+):KBaGd(WO(4))(3) 晶体光谱性质的研究表明，它表现出宽的吸收和发射带，这归因于 Nd(3+)中心周围局部无序的环境。宽吸收带适合二极管激光泵浦。
