Autor: Kyoko Noda, Satoshi Iwatsuki, Sumitaka Itoh, Hideo D. Takagi

Publikováno v: Platinum Metals Review. 48:117-124

Piezochromic phenomena are explained by pressure perturbation to the HOMO and/or LUMO energy levels of the related electronic transition. The piezochromism of solid inorganic and organic materials has been investigated by examination of the phase tra
