摘要

本文用红外光谱法研究了[Y(TMHD) 3]、[Cu(TMHD) 2]和[Ba(TDFND) 2 .四胺]在总压力为10托、温度范围为200 ~ 650℃、无氧和有氧条件下的气相热分解。每一种配合物的分解特性随温度的变化以及吸收系数的变化都与分子结构有关。

A study by In Situ FTIR Spectroscopy of the Decomposition of Precursors for the MOCVD of High Temperature Superconductors
In this paper we report on a study by FTIR spectroscopy of the gas phase thermal decomposition of [Y(TMHD) 3 ], [Cu(TMHD) 2 ] and [Ba(TDFND) 2 .tetraglyme] under a total pressure of 10 Torr, for a temperature range 200 - 650°C, and in the absence and presence of oxygen. The variation of the decomposition characteristics for each of the complexes as a function of temperature, and as shown by changes in the absorption coefficients, are related to the molecular structures.
