The high solubility of CdS is ascribed to the dissociation of metal-metal bonds and edge-shared tetrahedra in these Ga-containing glasses.

CdS高的含量可归因于含Ga硫系玻璃中金属-金属键和共边连接四面体的分离。

In early stage, suflides and selenides instead of tellurides were in focus, and little metal-metal interaction exists in these layered chalcogenides.

从结构特征看，已有的层状三组元硫族化合物中没有或少有金属-金属相互作用。

It is the first example foundin tellurides that the third component inserts the intra-layer region as well as the interlayer one. This statisticoccupation of Ni atom between layers also produces variouschemical environments around metal and non-metal atoms in thiscompound.

第三组元金属插入层内的同时也插入层间，这在碲化物中是很少见到，并使该化合物中金属和非金属的局部化学环境多样化。

Using tellurium power and corresponding simple metal salts as reactants, we have prepared a series of nanocrystalline metal tellurides (Cu〓Te〓, CoTe〓, NiTe〓, SnTe, Ag〓Te, CdTe, PbTe) in ethylenediamine system at low temperature (140-180℃).

通过乙二胺体系的溶剂热过程，以碲粉为碲源，从简单金属盐出发，在较低的温度下（140-180℃）成功地制备了一系列纳米金属碲化物(Cu〓Te〓、CoTe〓、NiTe〓、SnTe、Ag〓Te、CdTe、PbTe)。
