碲

A brittle silver-white metalloid element that is related to selenium and sulfur; it is used in alloys and as a semiconductor; occurs mainly as tellurides in ores of copper and nickel and silver and gold.

一种脆的、银白色非金属元素，与硒和硫有关联，用于合金及作半导体，主要作为碲化物存在于铜、镍、银、金矿石中。注意，注意力集中

The low temperature solvothermal route was extended to synthesize nanocrystalline tellurides.

发展了低温溶剂热合成碲化物纳米晶的技术。

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。

Under atmospheric pressure, binary nanocrystalline sulfides and selenides such as CdS、CdSe、PbS、 PbSe、Cu〓Se、Ag〓S、Ag〓Se、SnSe are obtained at room temperature; nanocrystalline CdTe and PbTe are obtained by heating. Nanocrystalline NiSe〓、CoSe〓 and FeTe〓 are obtained by hydrothermal conditions.

根据硫、硒歧化的碱溶液与碲歧化的碱溶液稳定性的不同，发现在室温条件下可成功获得CdS、CdSe、PbS、PbSe、Cu〓Se、Ag〓S、Ag〓Se、SnSe等二元硫化物与硒化物纳米晶；加热条件下可成功获得CdTe与PbTe纳米晶；而NiSe〓、CoSe〓及FeTe〓的合成则要在水热条件下进行。

In order to understand the mechanism of carrier recombination process, the TRPL was also investigated. The coverage dependence of lifetime can be well-explained by band-bending effect and electron-hole wave function overlap.

由时间解析光谱来分析载子生命期，我们发现载子生命期会随著碲化锌覆盖厚度的不同而改变，其现象可由能带弯曲的情形，以及电子电洞波函数的重叠情形加以说明。

The cut-off wavelength of the fiber is about 1270nm. The dispersion of the fiber is about -25ps/nm~*km at 1550nm. The MFD the fiber is about 7.12μm at 1550nm. These optic properties are suitable for EDFA application.
