Formation of self-assembled monolayers of silver sulphide nanoparticles

Nanosize silver sulphide semiconductor particles were synthesized using the nonionic surfactant, Triton X-100. A blue shift is obtained as compared with the optical band edge of bulk silver sulphide. Onto the glass or mica slides, self-assembled monolayers (SAMs) of bifunctional organic molecule were prepared on the gold or aluminum layers. By immersing them into the microemulsion of silver sulphide, the SAMs of nanosize silver sulphide particles were acquired. Further, The surface characterization about SAMs of nanoparticles was studied.
