Abstract

In this study, CdTeS (nanocrystals) which are known as quantum dots were colloidally synthesized in form of water-dispersible. Analysis and characterization of obtained nanocrystals were carried out by UV-vis and fluorescence spectrophotometry, TEM and XRD techniques. These particles that have been facility of application in electronic and biological areas were used to detect some pollutants with sensor applications. Because of that the obtained CdTeS nanocrystals have fluorescence properties and their spectroscopic properties have been changed by interaction with materials around them, they were used to detect alkaline and alkaline earth metal ions such as Ba2+, Ca2+, K+, Li+, Mg2+, Na+, Sr2+ in development of optic sensor. According to the obtained results, the highest fluorescence quenchnig was observed for Mg2+ ions.

Özet

Bu çalışmada kuantum nanokristaller olarak bilinen CdTeS yapıları suda dağılabilen şekilde kolloidal olarak sentezlenmiştir. Elde edilen nanokristallerin analizleri ve karakterizasyonu UV-vis ve floresans spektorofotometrisi, TEM (transmission electron microscope-geçirimli elektron mikroskobu), XRD (X-ray diffractometer-X ışını kristalografisi), teknikleri ile yapılmıştır. Elektronik ve biyolojik amaçlı birçok alanda uygulama imkânı sağlayan bu parçacıklar, sensör uygulamaları ile bazı suda bulunan kirletici maddelerin tayini için kullanılmıştır. Elde edilen CdTeS nanokristallerinin floresans özellik göstermeleri ve ortamdaki maddelerle etkileşimleri sonucunda spektroskopik özelliklerinin değişmesi sayesinde, Ba2+, Ca2+, K+, Li+, Mg2+, Na+, Sr2+ gibi alkali ve toprak alkali metalleri tayini için optik sensör geliştirilmesinde kullanılmıştır. Elde edilen bulgulara göre en yüksek floresans sönümlenmesi Mg2+ iyonları için gözlenmiştir.
