Abstract (EN): Synthesis, characterization, and the optical behavior of CdS quantum dots nanoparticles, confined in zeolites, following a new synthesis approach in different natural zeolites mordenite, clinoptilolite, and syntheticZSM-5, were carried out. The composite materials are characterized by x-ray diffraction, Fourier transmission infrared spectroscopy, energy dispersive, scanning and transmission electron microscopy. After CdS-QDs formation, the synthesized materials become fluorescent with emission wavelengths (average and standard deviation of the maximum wavelength; full width of half maximum): Mordenite-CdS QDs (628 +/- 5 nm; 272 nm); clinoptilolite-CdS QDs (585 +/- 8 nm; 284 nm), and ZSM-5-CdS QDs (579 +/- 4 nm; 214 nm).
