Abstract：

Ultrasound-assisted　bulk　synthesis　of　CdS-PVK　nanocomposites　through　reversible　addition　fragmentation　chain　transfer　(RAFT)　polymerization　was　carried　out.　CdS　nanoparticles　exhibited　outstanding　properties　including　high　carrier　generation　efficiency　and　mobility,　discreet　energy　bands,　and　narrow　emission　profiles.　The　use　of　the　ultrasonic　irradiation　in　chemical　reaction　was　found　to　be　advantageous　due　to　significant　decrease　in　the　time　required　to　carry　out　reaction　and　to　the　considerable　improvement　in　yield　of　the　target　product.　The　photoluminescence　(PL)　spectrum　of　pure　DDAT-PVK　reference　exhibited　a　strong　emission　peak　at　about　448　nm,　whereas　pure　CdS-OH　nanoparticles　showed　two　broad　emission　peaks　at　about　451　and　624　nm.　The　CDS-PVK　nanocomposites　exhibited　a　decrease　in　transmittance　about　the　focus　typical　of　an　induced　positive　nonlinear　absorption　of　incident　light　whereas　the　pure　nanocomposites　exhibited　no　nonlinear　optical　response　of　its　own.
