Abstract

Thioglycolic acid (TGA) coated CdTe quantum dots (QDs) in several particle sizes having red and blue colors were stabilized in solid phase by a water dispersible polymer (wdp). Absorption and fluorescence spectra showed that the as-prepared CdTe QDs had good photoluminescence property. A kind of self-assembly aggregation of the prepared CdTe-wdp nanoparticles was observed as the first time in solid phase. The QDs were characterized by Fourier transform infrared spectroscopy (FTIR), Atomic force microscopy (AFM), Scanning electron microscopy (SEM), Energy Dispersive X-ray spectroscopy (EDS), Steady state fluorescence spectroscopy and fluorescent imaging using BAB Image Analysis System®, Transmission-electron microscopy (TEM) and X-ray powder diffraction (XRD).

Özet

Kırmızı ve mavi renklere sahip olan çeşitli parçacık boyutlarında tiyoglikolik asit (TGA) kaplanmış CdTe kuantum noktaları (QD'ler), katı fazda suda dağılabilir bir polimer (wdp) ile stabilize edildi. Absorpsiyon ve floresan spektrumları, hazırlanan CdTe QD'lerin iyi bir fotolüminesans özelliğine sahip olduğunu gösterdi. Hazırlanan CdTe-wdp nanopartiküllerinin bir tür kendiliğinden toplanma agregasyonu, katı fazda ilk kez gözlenmiştir. QD'ler, Fourier transform infrared spektroskopisi (FTIR), Atomik kuvvet mikroskopisi (AFM), Taramalı elektron mikroskobu (SEM), Enerji Dağılımlı X-ışını spektroskopisi (EDS), Sabit durum flüoresans spektroskopisi ve BAB Görüntü Analiz Sistemi® kullanılarak floresan görüntüleme, Transmisyon-elektron mikroskobu (TEM) ve X-ışını toz kırınımı (XRD) ile karakterize edildi.
