Synthesis, growth and characterization analysis of nickel mercury thiocyanate crystal (NMTC)

Vickers microhardness studies on Cobalt Mercury Thiocyanate single crystals grown in silica gel

“…The Meyer's index number was calculated from the Mayer's law [20] which gives the relation between the load and indentation diagonal length. The relation is given as P = k 1 d n (2) where k is the materials constant and n is the Meyer's index. From the graph (Fig 2b) between the values of log p and log d, the Value of n was obtained from the slope of a straight line after leastsquare fitting .The value of n is greater than 2 (n= 2.7206).…”

“…In the past three decades, nonlinear optical metal coordination compounds have been discovered and are found to be more interesting because of their wide applications in the fields of optical computing, optical information processing, telecommunication, optical disk data storage, laser remote sensing and medical diagnostics [1][2]. Organometallic coordination complexes have the potential of combining the high optical nonlinearity and structural flexibility of organic materials with the thermal and mechanical stability of inorganic materials [3,4].…”
