| 説明 | The greenish-glowing material on this rock is hyalite opal (SiO2·nH2O - hydrous silica), also known as glass opal. Hyalite is composed of opal-AN, which refers to amorphous opal having a network structure similar to silica glass, rather than opal consisting of silica gel spheres/colloids (most opal is the latter type).Hyalite opal glows (fluoresces) green under ultraviolet light (black light). Fluorescence results from short-wavelength ultraviolet radiation, long-wavelength ultraviolet radiation, or x-rays bombarding atoms. This causes electron excitation, but the electrons do not remain in an energetically excited state - they quickly give off energy and resume their normal energy levels. If the electron energy release is in the visible spectrum of light, a mineral glows, or fluoresces. |
