“…The basic units of the zeolite framework are constructed by connecting the corner-sharing TO 4 tetrahedra (T = Si, Al) of silicon–oxygen tetrahedra [SiO 4 ] 4– and aluminum–oxygen tetrahedra [AlO 4 ] 5– , often the Al 3+ can be substituted by P 3+ or Ga 3+ . − Owing to the superior advantages of efficient ions exchange capacity that allows the easily intake of Ag + , uniform molecular-sized cage structure that benefits the confinement of functional clusters, and high chemical and thermal stability that enable long lasing applications, the zeolites have been considered as desirable hosts for Ag NCs. − It has been reported that after thermal treatment, X-ray or electron beam irradiation on the Ag + -exchanged zeolites, Ag 2 + , Ag 3 n + , Ag 4 n + , and Ag 6 n + may be formed in the D6r or sodalite cages of zeolites. ,,, The formation efficiency and luminescence properties of Ag NCs can be manipulated through the selection of zeolite topological structure, framework, and extra-framework modifications, adjustment of silver loading degree, and thermal treatment. For example, recent studies indicated that the Ag NCs confined inside Linda A (LTA) and FAU zeolites exhibit blue-shifted emission when the radius of the extra-framework cation is reduced, and show significantly higher emission intensity in the Li + -type zeolites than in the Na + /K + /Ca 2+ -type zeolites; − the peak emission wavelength of Ag NCs can be turned over 40 nm through desilication or dealumination treatment on the host FAU zeolites before Ag + -exchange; the Ag NCs in Li-LTA zeolites exhibit red-shifted emission from blue to green-yellow with increasing hydration level. , …”
