Abstract

In this study, the energy gap-refractive index relations of perovskites are examined in detail. In general, the properties of perovskites are dependent on the structural reorganization and covalent nature of their octahedral cages. Based on this notion, a simple relation governing the energy gap and the refractive index is proposed for perovskites. The results obtained with this relation are in good accord with the literature values and are consistent with some well-established relations.

摘要

在本研究中，详细考察了钙钛矿的能隙-折射率关系。一般来说，钙钛矿的性质取决于其八面体笼的结构重组和共价性质。基于这一概念，提出了一个适用于钙钛矿的能隙和折射率的简单关系。用该关系得到的结果与文献值吻合良好，并且与一些已确立的关系一致。
