20.500.12556/DKUM-85263 Mehanokemijska sinteza nanodelcev ternarnih kadmijevih halkogenidov diplomsko delo univerzitetnega študijskega programa I. stopnje Mechanochemical synthesis of ternary cadmium chalcogenides nanoparticles Binarni kadmijevi halkogenidi (CdS, CdSe, CdTe) so zaradi svojih termoelektričnih, polprevodniških in optičnih lastnosti pomembni materiali v fotovoltaiki in fotoprevodnosti, medtem ko so ternarne spojine s halkogenidi (CdSₓSe₁₋ₓ, CdSₓTe₁₋ₓ in CdSeₓTe₁₋ₓ) pomembne katalitske snovi. V sklopu diplomske naloge smo mehanokemijsko sintetizirali binarne (CdS, CdSe, CdTe) in ternarne (CdSₓSe₁₋ₓ, CdSₓTe₁₋ₓ in CdSeₓTe₁₋ₓ) kadmijeve halkogenide v obliki nanodelcev. Sintezo smo izvajali s planetarnim mikromlinom, pri čemer smo ugotavljali, kakšen čas je potreben za učinkovito sintezo nanodelcev. Po končani sintezi smo učinkovitost sinteze in karakteristike sintetiziranih nanodelcev preverili z diferenčno dinamično kalorimetrijo, s termogravimetrično analizo, z rentgensko praškovno difrakcijo, z dinamičnim sipanjem svetlobe in s transmisijsko elektronsko mikroskopijo. Binary cadmium chalcogenides (CdS, CdSe, CdTe) are important materials in photovoltaics and photoconductivity due to their thermoelectric, semiconducting and optical properties, while ternary compounds with chalcogenides (CdSₓSe₁₋ₓ, CdSₓTe₁₋ₓ in CdSeₓTe₁₋ₓ) are important catalytic materials. In this work, binary (CdS, CdSe, CdTe) and ternary (CdSₓSe₁₋ₓ, CdSₓTe₁₋ₓ in CdSeₓTe₁₋ₓ) cadmium chalcogenides nanoparticles were mechanochemical synthesised. The synthesis was performed using a planetary micro mill, where the time required for efficient synthesis of the nanoparticles was determined. After the synthesis, its efficiency and characteristics of the synthesised nanoparticles were confirmed using a differential scanning calorimetry, thermogravimetric analysis, X-ray powder diffraction, dynamic light scattering and transmission electron microscopy. mehanokemijska sinteza planetarni mikromlin kadmijevi halkogenidi nanodelci karakterizacijske tehnike nanodelcev mechanochemical synthesis planetary micro mill cadmium chalcogenides nanoparticles nanoparticle characterisation technique true true false [N.
