Dusuk maliyetli bir Raman cihazı karbon nanotup analizi gerceklestirmek amacıyla

modifiye edilmis ve gelistirilen sistemle nanotup spektrumları basarı ile olculmustur. Ancak,

geleneksel ve kapsamlı Raman mikroskoplarına kıyasla, nanotup orneklerinin uygun substratlar

uzerine ince filmler halinde kaplanmıs olması gerektiği bulunmustur. Su ve dimetilformamid

(DMF) gibi dispersiyon ortamları ile sodyum dodesil sulfat (SDS) ve Triton X-100 gibi yuzey

aktif maddeler nanotup dispersiyonunun kararlılığına etkileri acısından incelenmistir. Ayrıca,

filmin hazırlanacağı yuzey malzemesinin film homojenliği ve spektrum tekrarlanabilirliği

acısından oldukca kritik olduğu gosterilmistir. En iyi filmler Triton X-100 ile hazırlanan

dispersiyonların Sn substratlar uzerine damlatılması ile elde edilmistir.

Modification Of A Low Cost Raman Spectrometer For Carbon Nanotube Analysis

Öz

A low cost Raman device was modified and utilized successfully for the carbon

nanotube analysis. However, as opposed to traditional comprehensive Raman microscopes,

samples were found to be coated as thin films on certain substrates. The effect of dispersing

media, such as water and dimethylformamide (DMF) and the effect of surfactants such as

sodium dodecyl sulfate (SDS) and Triton X-100 on the dispersion stability were tested.

Substrate material on which the dispersion was dried, was demonstrated to be crucial in terms

of the film homogeneity and spectrum repeatability. The highest quality films were obtained on

Sn substrates and Triton X-100 was the most appropriate surfactant.
