EN

Thin films of CdS have been deposited on glass substrates using the chemical spray pyrolysis method at different substrate temperatures of 100°C, 150°C, 200°C, and 250°C to investigate the optimum temperature to prepare CdS particles with nano dimensions. The CdS thin film was examined using SEM, X-ray spectrum analysis, and UV-visible spectrophotometry. The SEM images and X-ray spectra were used to estimate the structural features and grain size of the films. The optical properties and optical constants also varied clearly with temperature. In addition, the energy gap changed with temperature from 2.1 eV to 2.55 eV.

Wpływ temperatury podłoża na właściwości optyczne i strukturalne nanocząstek CdS Cienkie warstwy CdS zostały osadzone na szklanych podłożach metodą chemicznej pirolizy natryskowej w temperaturach podłoża wynoszących 100°C, 150°C, 200°C i 250°C w celu określenia optymalnej temperatury do przygotowania cząstek CdS o wymiarach nano. Tak przygotowane próbki zostały zbadane za pomocą SEM i spektrofotometrii UV-VIS, przeprowadzono także analizę widma rentgenowskiego. Obrazy SEM i widma rentgenowskie zostały wykorzystane do oszacowania cech strukturalnych i wielkości ziarna warstw. Właściwości optyczne i stałe optyczne zmieniały się wyraźnie wraz ze zmianą temperatury. Przerwa energetyczna wynosiła w zależności od temperatury od 2,1 eV do 2,55 eV.
