Web12 de abr. de 2024 · The UV–vis absorption intensity of DP5Br3PyBP-MTSC gradually decreased after visible light irradiation for a certain time. However, the UV–vis absorption curve did not return to the original state, this is attribute to the stronger induction effect of UV light than that of visible light, leading to the inability of the first complete return of the … WebColor centers are imperfections in crystals that cause color (defects that cause color by absorption of light). They are most often due to radiation damage: e.g., damage due to exposure to gamma rays. This irradiation may be from both natural (U, Th, K in minerals) or artificial sources. In rare cases, UV light can produce color centers.
