Özet:

 In this work, magnetic nitrogen doped graphene quantum dots iron oxide-polypyrrole NGQDs-Fe3O4PPy ternary nanocomposite having perfect photothermal activity was synthesized. The chemical structure and morphological of the synthesized nanocomposites were characterized by ultraviolet-visible UV-Vis spectroscopy, Fourier transform infrared FTIR, X-ray diffraction spectroscopy XRD, high-resolution transmission electron microscopy HRTEM, X-ray photoelectron spectroscopy XPS. Photothermal properties of the synthesized nanocomposites were examined at different laser power densities 1.5 - 2.5 Wcm2 in the near infrared NIR region 808 nm using aqueous solutions of different concentrations 0.025 - 0.1 mg  mL. The maximum temperature Tmax of NGQDs-Fe3O4PPy composite reached up to 54.3C and 83.1C under irradiation of the 808 nm NIR laser at 1.5 and 2.5 Wcm2 power density for 10 min at 0.1 mgml concentration. The synthesized NGQDs-Fe3O4PPy triple nanocomposite with high photothermal performance and photothermal stability is thought to have an important potential for photothermal treatment applications.

 Bu çalışmada, yüksek fototermal aktiviteye sahip azot katkılı grafen kuantum nokta-demir oksit-polipirol NGKN-Fe3O4PPy üçlü nanokompoziti sentezlenmiştir. UV-görünür bölge spektroskopisi UV-vis, Fourier dönüşümlü kızıl ötesi spektroskopisi FTIR, X-ışını kırınım yöntemi XRD, yüksek çözünürlüklü geçirimli elektron mikroskobu HRTEM, X-Ray fotoelektron spektroskopisi XPS ile sentezlenen yapıların morfolojik ve kimyasal yapıları karakterize edilmiştir. Ayrıca fototermal özelikleri farklı derişimlerdeki 0,025  0,1 mgmL sulu çözeltileri kullanılarak yakın kızılötesi NIR bölgesinde 808 nm farklı lazer güç yoğunluklarında 1,5  2,5 Wcm2 incelenmiştir. 808 nm NIR lazer ile 10 dk uyarım sonucunda 0,1 mgml derişimli NGKN-Fe3O4PPy kompozitinin maksimum sıcaklığının 1,5 ve 2,5 Wcm2 güç yoğunluklarında sırasıyla 54,3C ve 83,1Cye ulaştığı saptanmıştır. Sergilediği yüksek fototermal performans ve fototermal kararlılık sayesinde sentezlenen NGKN-Fe3O4PPy üçlü nanokompozitinin fototermal tedavi uygulamaları için önemli bir potansiyele sahip olduğu düşünülmektedir.
