Kuantum noktalar (QDs) sahip oldukları benzersiz optik ve elektronik özellikleri ile son yıllarda birçok
farklı teknolojik alanda popüler hale gelmişlerdir. Bu durum QD'lar ile organik bileşiklerin etkileşimine
olan ilgiyi arttırmaktadır. Bu çalışmada bu ilgiye temel alarak, CdSeTe QD'lar ile Brom Krezol Moru (BCP)
kloroform içerisinde oda sıcaklığın da etkileşimini ve CdSeTe QDs/BCP yapısının spektroskopik olarak
karakterizasyonu açıklamayı amaçlamıştır. Bu amaç doğrultusunda CdSeTe QDs/ BCP oluşumunun
etkileşimleri spektroskopik olarak Fourier dönüşümlü kızılötesi spektroskopisi (FTIR), absorbans ve
emisyon üzerinden karakterizasyon çalışmaları yapılmıştır. BCP'nin CdSeTe QD'lar ile hibritleşmesiyle
QDs'nin lüminesans pikinde 19 kat azalma tespit edilmiştir. Bununla birlikte Brom Krezol Moru (BCP) ile
hibritleşen CdSeTe QD'lar BCP'nin soğurma özelliğini 112.8 katına kadar arttırmıştır.

Spectrophotometric Evaluation of Combination of CdSeTe Quantum Dots and Bromocresol Purple

Öz

Quantum dots (QD) have been used in many different technological fields in recent years with their
unique optical and electronic features. This increases the relevance to hybrid structures compatible
with QDs. In this study, CdSeTe QDs and Bromocresol Purple (BCP) hybridized in chloroform in a very
short time of room temperature and CdSeTe QD / BCP hybrid structures were created. The interactions
of synthesized CdSeTe QD / BCP hybrid structures were examined by FT-IR and absorbance and
emission characterization studies were carried out. A 19-fold reduction in the luminescence peak of QD
was detected by hybridizing BCP with CdSeTe QDs. However, CdSeTe QDs hybridized to BCP increased
the absorbance property of BCP up to 112.8 times.
