Preparation and characterization of CdS nanoparticles by ultrasonic irradiation

Biosynthesis of CdS nanoparticles: An improved green and rapid procedure

“…Among these, CdS has been extensively studied due to its potential technological applications in field effect transistors, solar cells, photovoltaic, light emitting diodes, photocatalysis, photoluminescence, infrared photodetector, environmental sensors and biological sensors [5][6][7][8][9][10][11]. The preparation of CdS nanoparticles has been carried out using various methods such as microwave heating [12], microemulsion synthesis [13][14][15][16], chemical synthesis [8,14,[17][18][19][20][21], photoetching [22] and ultrasonic irradiation [23].…”

Biosynthesis of cadmium sulphide quantum dots by usingPleurotus ostreatus(Jacq.) P. Kumm

“…[7,8] The preparation of CdS QDs has been carried out using various methods, such as microwave heating, microemulsion synthesis and ultrasonic irradiation. [9,10] However, the chemical methods are complicated, outdated, costly, inefficient and have low productivity, produce hazardous toxic wastes raising environmental safety issues and human health concerns. Therefore, an alternative approach suggests the use of biological systems for synthesis of nanomaterials in order to produce nanoparticles at ambient temperature and pressure without requiring hazardous agents and generating poisonous by-products.…”

Sonochemical synthesis of PbS nanorods

“…of ∼5000 • C, pressures of ∼1000 atm, and heating and cooling rates above 10 10 K/s by acoustic cavitation. This method has been widely explored to generate metals, metal sulfides and metal oxides [13][14][15].…”
