Crystal field theory has been used to calculate the spin allowed transition of Fe2+ ions with 3d6 configuration in the two substitutional sites of interest in tourmaline, i. e., in b and c-sites which have Cs and C_1 point group respectively, by using Zhao's SCP d-orbit of Fe2+ ion. The transition of Fe~(2+)-Fe3+ ion pairs, (Fe2+[g]-Fe3+)→(Fe2+[e]-Fe3+) which has not previously been studied, is discussed here theoretically. An estimate of the magnitude of the intensity of the three strongly polarized (E⊥c>>E//c)...

Crystal field theory has been used to calculate the spin allowed transition of Fe2+ ions with 3d6 configuration in the two substitutional sites of interest in tourmaline, i. e., in b and c-sites which have Cs and C_1 point group respectively, by using Zhao's SCP d-orbit of Fe2+ ion. The transition of Fe~(2+)-Fe3+ ion pairs, (Fe2+[g]-Fe3+)→(Fe2+[e]-Fe3+) which has not previously been studied, is discussed here theoretically. An estimate of the magnitude of the intensity of the three strongly polarized (E⊥c>>E//c) bands near 9,000cm~(-1),13,800cm~_(-1),15,000cm~(-1) in the near-infrared region is given. The interpretation of the near-infrared absorption spectra of tourmaline is satisfactory.

In this paper, we have reported the special spectrum of intracenter electronic transition on EL2 deep level and its fine structure including six peaks using near infrared absorption method and low-temperature measurement and investigated the coupling mechanism between intracenter electronic excitation and traverse acoustic phonons. Optical quenching effect has been observed and a metastable state model is proposed here. The relationship between EL2 infrared absorption and temperature ranging from 10K to 300K is given. The 115K was determined as the temperature transformation point from metastable stata to stable state. Based on the EL2 intra-structure information obtained from the experimental results, EL2 level theoretic model has been suggested.

The near-infrared characteristics at room temperature and low temperature of the fluid encapsulated CZO kralski (LEC) undoped semi-insulating GaAs have been studied, and the mechanism of main deep electron trap(EL2) which causes infrared absorption has also been investigated. By using a low temperature high resolution technique, the EL2 intraccnter transition characteristic band, and the fine structure composed of zero-phonon line and five phonon coupling peaks have been found in the sample, zero-phonon line and the near-infrared absorption band have the same photo-quenching effect. There is an excellent linear relation between its intensity and EL2 concentration. Thus, a new method for determining EL2 concentration is provided.

本文研究液封直拉(LEC)未掺杂半绝缘GaAs室温和低温近红外吸收特性,对主要深电子陷阱(EL2)引起红外吸收的机理进行了探讨。利用低温高分辩率技术,发现样品中EL2内部跃迁特征谱及由零声子线和五个声子耦合峰组成的精细结构。零声子线与近红外吸收带具有相同的光淬灭效应,其强度与EL2浓度具有良好的线性关系,由此阐述了一种测定EL2浓度的新方法。
