| Abstract Scope |
Zeolites are crystalline porous materials with significant applications in greenhouse gas capture like CO2 and NOx, heavy metals, hydrocarbons and other dangerous contaminants for the environment. The addition of luminescent species like Eu3+ or Ag multimers could provide sensing functionality to these materials. The red emission of Eu3+ has a clear and identifiable spectral shape and a long luminescence lifetime, while Ag multimers provide an intense blue emission. Both of them could potentially respond to the absorption and desorption of contaminant species. Optimization of the synthesis process supported by a detailed structural and optical characterization will be presented for 13X zeolites, as well as preliminary testing on the capture and sensing capabilities of the material. |
