Abstract: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.

Title:Mechanochemical synthesis of ternary cadmium chalcogenides nanoparticles
Abstract: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.
Keywords:mechanochemical synthesis, planetary micro mill, cadmium chalcogenides, nanoparticles, nanoparticle characterisation technique
