ZnS KUANTUM NOKTALARI İLE MODİFİYE EDİLMİŞ CoFe2O4 NANOYAPILARININ HAZIRLANMASI

Öz

Nanoteknoloji son yüzyılda popüler bir kavram haline geldi. Hatta günlük hayatın birçok alanında insan hayatını kolaylaştıracak uygulamalarda kullanılmaya başlanmıştır. Bu nedenle bilim insanları nanoteknoloji üzerine yoğunlaşmışlardır. Temel bilimlerde nanokimya ve nanomalzeme alanları gelişmiş ve bu alanlarda bilimsel ve teknolojik gelişmeler hız kazanmıştır. Nanopartiküller son derece işlevsel yapıları sayesinde malzeme geliştirme ve üretimi alanında temel araçlar haline gelmiştir. Manyetik partiküller, manyetik özellikleri sayesinde biyomedikal, elektronik, enerji depolama, katalizör ve sensör çalışmaları için cazip hale gelmiştir. Ancak özellikle metal oksit manyetik parçacıkların optik özelliklerinin (yüzey plazmon rezonansı, iletkenlik ve lüminesans ışın saçılımı gibi) eksikliği bu tür parçacıkların önemli eksiklikleri arasındadır. Bu eksiklikler kompozit yapılarak ya da farklı malzemelerle işlevselleştirilerek giderilmektedir. Bu çalışmada manyetik partiküller (CoFe2O4) floresan ZnS kuantum noktaları ile birleştirilerek fotokatalist veya sensör uygulamalarında kullanıma hazır hale getirilmiştir

Preparation of CoFe2O4 Nanostructures Modified with ZnS Quantum Dots

Abstract

Nanotechnology has become a popular concept in the last century. It has even begun to be used in many areas of daily life in applications that will make human life easier. For this reason, scientists have focused on nanotechnology. The fields of nanochemistry and nanomaterials have been developed in basic sciences and scientific and technological developments have accelerated in these fields. Nanoparticles have become fundamental tools in the field of material development and production thanks to their highly functional structures. Magnetic particles have become attractive for biomedical, electronics, energy storage, catalyst and sensor studies thanks to their magnetic properties. However, especially the lack of optical properties of metal oxide magnetic particles (such as surface plasmon resonance, conductivity and luminescence emmision) are among the important shortcomings of such particles. These deficiencies are eliminated by making composites or functionalizing them with different materials. In this study, magnetic particles (CoFe2O4) were combined with fluorescent ZnS quantum dots and made ready for use in photocatalyst or sensor applications.
