Nanosecond laser irradiation synthesis of CdS nanoparticles in a PVA system

- CdS quantum dots in PVA polymer matrices were prepared.
- Nucleation and growth occurred via nanosecond laser irradiation.
- PVA effectively passivated the surface of the CdS.
- CdS nanoparticles obtained are spherical and crystalline.
- Strong blue shift in the band gap was observed in the UV-vis spectra.
