查询词典 H

The modification occurred in crystal lattice and the restoration effect of annealing are discussed by analyzing the intensity, width and angle of the X-ray diffraction peaks. The H〓 concentration and related structural information are deduced by the evolution of OH〓 absorption spectra with annealing, which offers the experimental proof for further discussion on annealing. The disappearance of the OH〓 absorption peak at 3300cm〓 after annealing indicates that some H〓 of high concentration diffused further into the substrate and the crystal phase changes accordingly.

根据质子交换波导退火前后在OH〓吸收峰特征的变化，推断波导层H〓浓度及相关的结构信息，并对进一步分析退火机制提供了实验依据；由于3300cm〓〓处的吸收峰代表的是立方钙钛矿的HNbO〓结构成分，因此退火后该峰的消失确实说明高浓度区域的H〓继续向波导深度迁移的事实，同时波导区的晶相成分也发生变化。
