20.500.12556/DKUM-90257 Sinteza ternarnih kadmijevih halkogenidov s planetarnim mikromlinom diplomsko delo univerzitetnega študijskega programa I. stopnje Synthesis of ternary cadmium chalcogenides by planetary micromilling Ternarni kadmijevi halkogenidi, kot so CdSexTe1-x, CdSxSe1-x in CdTexS1-x, so osnova sodobnih elektronskih naprav. Uporabljajo se kot laserji, fotodetektorji, v sončnih celicah, v piezoelektroniki, v svetlečih diodah, itd. Kvartarni halkogenid CdSxTexSe1-2x ima številne zanimive aplikacije zaradi svojih edinstvenih optoelektronskih lastnosti. Tako kot ternarni kadmijevi halkogenidi, se tudi CdSxTexSe1-2x uporablja v fotovoltaiki, zaradi svojih sposobnosti absorbiranja širokega spektra sončne svetlobe in učinkovite pretvorbe te energije v električno energijo, v svetlečih diodah in drugih optoelektronskih napravah, zaradi visoke fotoluminiscence, v različnih vrstah senzorjev in v termoelektričnih napravah. Pri diplomskem delu smo uporabljali mehanokemijsko sintezo, ki se v zadnjem času uporablja vse več. Z mehanokemijsko metodo, z uporabo planetarnega mikromlina, smo sintetizirali ternarne kadmijeve halkogenide (CdSexTe1-x, CdSxSe1-x, CdTexS1-x) in kvartarni kadmijev halkogenid CdSxTexSe1-2x. Spreminjali smo pogoje uporabljene v predhodnih raziskavah ter ugotavljala kako le-ti vplivajo na sintezo nanodelcev. Karakteristike sintetiziranih nanodelcev smo po koncu sinteze preverili z rentgensko praškovno difrakcijo, z dinamičnim sipanjem svetlobe, z diferenčno dinamično kalorimetrijo in s transmisijsko elektronsko mikroskopijo. Ternary cadmium chalcogenides, such as CdSexTe1-x, CdSxSe1-x and CdTexS1-x, form the foundation of modern electronic devices. They are used in lasers, photodetectors, solar cells, piezoelectronics, and light-emitting diodes. The quaternary chalcogenide CdSxTexSe1-2x has numerous interesting applications due to its unique optoelectronic properties. Similar to ternary cadmium chalcogenides, CdSxTexSe1-2x is utilized in photovoltaics for its ability to absorb a broad spectrum of sunlight and efficiently convert this energy into electricity, in light-emitting diodes and other optoelectronic devices for its high photoluminescence, in various types of sensors, and in thermoelectric devices. In the thesis, we employed mechanochemical synthesis, which has been increasingly used in recent times. Using the mechanochemical method with a planetary ball mill, we synthesized ternary cadmium chalcogenides CdSexTe1-x, CdSxSe1-x and CdTexS1-x and the quaternary cadmium chalcogenide CdSxTexSe1-2x. We varied the conditions used in previous research and examined how they affect the synthesis of nanoparticles. The characteristics of the synthesized nanoparticles were assessed after synthesis using X-ray powder diffraction, dynamic light scattering, differential scanning calorimetry, and transmission electron microscopy. nanomateriali ternarni kadmijevi halkogenidi mehanokemisjka sinteza planetarni mikromlin karakterizacijske metode nanomaterials ternary cadmium chalcogenides mechanochemical synthesis planetary micro mill characterisation methods true true false [J.
