Ardışık iyonik tabaka adsorpsiyon reaksiyonu (SILAR) yöntemi ile üretilen MgO ince filmleri üzerinde Cr katkı maddesinin etkisi araştırıldı. filmler üzerindeki UV-Vis spektroskopisi, XRD (X-ışını kırınımı), SEM (taramalı elektron mikroskobu) ölçümleri optik, yapısal ve morfolojik özellikleri araştırılmıştır. Katkısız katkılı filmlerin spektroskopi ölçümleri, yükselmesine bağlı olarak, nano yapı...

ZnO thin films were deposited by successive ionic layer adsorption and reaction (SILAR) method using a zinc nitrate and ammonium bath on glass substrates. The number of employed cycles were 50, 100 and 200. The films were studied by X-ray diffraction (XRD), optical absorption (UV–Vis) and m-Raman. Structural analysis by XRD shows that the as-deposited ZnO films have high-orientation along c-dir...

We report single-particle photoluminescence (PL) intermittency (blinking) with high on-time fractions in colloidal CdSe quantum dots (QD) with conformal CdS shells of 1.4 nm thickness, equivalent to approximately 4 CdS monolayers. All QDs observed displayed on-time fractions > 60% with the majority > 80%. The high-on-time-fraction blinking is accompanied by fluorescence quantum yields (QY) clos...
