Ultra-fast Laser Synthesis of Inorganic Semiconductor Nanoparticle (NP)

​Quantum dot semiconductors, is ideal for next-generation electronic and optoelectronic devices (such as LEDs and solar cells) because of their unique physical properties, due to the quantum confinement effect. The possibility of using hybrid nanocomposites to fabricate functional optoelectronic devices with a simple solution process suggests the feasibility of transferring this technique to plastic substrates, an achievement that would offer many attractive advantages. In particular, semiconductor nanoparticles (NP) semiconductors have different applications, including biological, electrical and optoelectronic applications.

We found a novel, low cost, simple and facile technique to synthesize many NP materials by femtosecond laser ablation in liquid media without using chemical methods as the procedure does not involve any vacuum set up neither it needs any environmental control such as temperature or gas environment and cane be scaled up for industrial production.
