Abstract

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.

Development of Fluorescence-Based Optical Chemical Sensors for Detecting of Ionic Species Soluble In Water By Using Quantum Nanocrystals

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.
