20.500.12556/DKUM-96084 Green mechanochemical synthesis of binary and ternary cadmium chalcogenides with tunable band gaps In this work, we report on the mechanochemical preparation and characterization of binary (CdS, CdSe, and CdTe) and ternary (CdS0.5Se0.5, CdS0.5Te0.5, and CdSe0.5Te0.5) cadmium chalcogenides. The compounds were synthesized in a planetary micro mill using a zirconia grinding bowl and zirconia grinding balls. The products were examined by powder X-ray diffraction (pXRD), transmission electron microscopy (TEM), energydispersive X-ray spectroscopy (EDX), dynamic light scattering (DLS), UV–Vis spectroscopy, and differential scanning calorimetry (DSC). Interestingly, CdO formed as a by-product only during milling of Cd+S and Cd+Se in air, while it was absent in the Cd+Te and all ternary systems. The materials were obtained in the form of irregularly shaped aggregates measuring up to several hundred nanometers, composed of nearly spherical primary nanoparticles with diameters in the 10–20 nm range. The band gap energies calculated using Tauc plots for CdS0.5Se0.5, CdS0.5Te0.5, and CdSe0.5Te0.5 were 2.01 eV, 1.72 eV, and 1.53 eV, respectively. These results demonstrate the expected tunability of band gaps in ternary cadmium chalcogenides and attest to the potential of such materials for semiconducting applications, particularly in solar cells. The mechanochemical approach is once again shown to be a simple and effective method for the preparation of both binary and ternary chalcogenides, avoiding the use of solvents, toxic precursors, and energy-consuming reaction conditions. cadmium sulfide selenide telluride ternary compounds mechanochemistry band gap kadmij sulfidi teluridi mehanokemija ternarne spojine true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/jmmp © 2025 by the authors Članek v reviji 2025-12-01 13:52:08 2025-12-01 13:52:09 2025-12-02 03:10:24 0000-00-00 00:00:00 2025 0 0 17 str. iss. 11, [article no.] 375 Vol. 9 Nov. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-09-29 2025-11-13 2025-11-15 544.463 258719491 10.3390/jmmp9110375 2504-4494 jmmp-09-00375-v2_(1).pdf jmmp-09-00375-v2_(1).pdf 1 5CC781ECB685F788F031562782CE013E 58fa45f716c7c359ad083e9ca708ad72f0c9a2d15118497b78d91999919f053c bb012f53-ceb4-11f0-9b38-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200995 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
