Semiconductor Ag_2S nanocrytsals with different morphologies were synthesized in quaternary W/0 microemulsion solution containing Triton X-100, cyclohexane and n-pentanol. And particularly, the synthesis of AgjS nanorods with lengths up to 2.0-3.5 /uun and aspect ratio of 20 - 70 has been reported for the first time. The reaction conditions were optimized through investigations on the influences of W_0 , the concentration of the reactant, and the aging time on the morphology and the sizes of the products. Transmission electron microscopy (TEM) was utilized to characterize the shape and size of the obtained products.

Key words: Ag_2S, NANOPHASE MATERIALS, MICELLE, CYCLOHEXANE, PENTANOL, STRUCTURE CHARACTERISTICS
