Polimer matrisine katkılı yarı iletken kuantum noktaları ile oluşturulan ve optik özellikleri ayarlanabilen hibrit polimer yapıları, son yıllarda elektronik uygulamalarda yüksek kullanım potansiyelleri ile dikkat çekmektedir. Bu çalışmada, poli(vinilalkol) (PVA) matrisini güçlendirmek ve optik özelliklerini arttırmak için üç tip Cd bazlı kuantum nokta (QDs) (CdX (X=Se, Te, SeTe)) kullanılmıştır. PVA/3 farklı Cd tabanlı QDs yapılarının optik, iletkenlik ve termal karakterizasyonları karşılaştırmalı olarak değerlendirildi. QDs'lerin eklenmesiyle birlikte PVA/QDs nanokompozit yapısının floresans özellikleri sergilediği yapılarındaki gözlemlendi. hibridizasyon yapıları PVA/QDs nanokompozit FT-IR spektrumu ile aydınlatılmıştır. Ayrıca DSC ile analiz edilen hibrit polimer yapıların termal stabilitesinin %7-9 arasında arttığı ve PVA/QDs hibrit polimerlerin erime noktasının 5 ile 7 °C arttığı tespit edilmiştir. En yüksek termal kararlılık ve erime noktası artışları PVA/CdSeTe QDs hibrit yapılarında gözlendi. PVA matrisine CdSe QDs'ler ve CdTe QDs'lerin eklenmesiyle hibrit polimer yapısının iletkenlik değeri 100 kat artarken, CdSeTe QDs'lerin eklenmesi iletkenliği 1000 kat artırmıştır. Benzer şekilde dielektrik sabiti ve dielektrik kayıp testlerinde de PVA/CdSeTe QDs hibrit polimer yapılarının sinerjik etki nedeniyle her iki tipe göre daha başarılı olduğu tespit edilmiştir.

Hybrid polymer structures formed with semiconductor quantum dots that are doped into the polymer matrix and whose optical properties can be adjusted have attracted attention with their high usage potential in electronic applications in recent years. In this study, three types of Cd-based QD (CdX (X=Se, Te, SeTe)) were used to strengthen the poly (vinyl alcohol) (PVA) matrix and increase its optical properties. Optical, conductivity and thermal characterizations of PVA/3 different Cd-based QDs CdSe QD-PVA nanocomposites structures were evaluated comparatively. With the addition of QDs, it was observed that the PVA / QDs nanocomposites structure exhibits fluorescence properties. Hybridization structures in PVA/QDs nanocomposites structures were illuminated by FT-IR spectrum. In addition, it was determined that the thermal stability of hybrid polymer structures increased between 7-9% and the melting point of PVA/QDs hybrid polymers increased by 5-7 °C which was analyzed by DSC. The highest thermal stability and melting point increases were observed in PVA/CdSeTe QDs hybrid structures. With the addition of CdSe QDs and CdTe QDs into the PVA matrix, the conductivity value of the hybrid polymer structure increased 100 times, while the addition of CdSeTe QDs increased the conductivity by 1000 times. Similarly, in dielectric constant and dielectric loss tests, it was determined that PVA / CdSeTe QDs hybrid polymer structures are more successful than both types due to the synergic effect.
