Abstract
A polyvinyl alcohol (PVA) nanocomposite thin film embedded with zinc sulfide (ZnS) quantum dots was fabricated by a drop-casting method. The ZnS-embedded PVA films were characterized with polarized optical microscopy (POM), ultraviolet-visible (UV-vis) spectroscopy and photoluminescence (PL) spectroscopy. The POM study clearly exhibits the photo-elasticity effects of the ZnS/PVA film when stress is added. Optical absorption spectra showed strong red shift for the ZnS quantum dots in the PVA matrix. Room-temperature PL spectra demonstrated that the pure ZnS quantum dots show cyan emission at 517 nm while ZnS/PVA thin film gives off blue PL with a strong broad peak at 478 nm and a shoulder peak at 536 nm.
