“…Millipore water was used for making aqueous solutions. Synthesis of calcite and its surface modification with ammonium oxalate was based on reported literature (Srikanth and Jeevanandam 2009). Gold nanoparticles were deposited on calcite by two different methods: electroless deposition and galvanic displacement reaction.…”

“…The electroless deposition was carried out on the surface modified calcite using silver nitrate and formaldehyde (Chou and Ren 2000). In the galvanic displacement reaction, silver nanoparticles deposited calcite, prepared by a previously reported method (Srikanth and Jeevanandam 2009), was used and the silver nanoparticles were galvanically displaced with gold nanoparticles (Liu and Yang 2006). More details on the deposition experiments are as follows.…”

“…85-0849), calcium oxalate monohydrate (JCPDS File No. 77-1160), and gold (04-0784); during the surface modification with ammonium oxalate, part of the calcite is converted into calcium oxalate (Srikanth and Jeevanandam 2009). The crystallite size of gold, calculated for the three samples prepared by electroless deposition using Debye-Scherrer's formula, was found to be about 38 nm.…”

Gold nanoparticles have been deposited on synthetic calcite substrate by galvanic displacement reaction and electroless deposition methods. A comparative study has shown that electroless deposition is superior compared to galvanic displacement reaction for uniform deposition of gold nanoparticles on calcite. Characterization of the samples, prepared by two different deposition methods, was carried out by X-ray diffraction, transmission electron microscopy, field emission scanning electron microscopy (FE-SEM) and diffuse reflectance spectroscopy (DRS) measurements. FE-SEM studies prove that smaller nanoparticles of gold are deposited uniformly on calcite if electroless deposition method was employed and DRS measurements show the characteristic surface plasmon resonance of gold nanoparticles.

“…To impart electrical conductivity to non-conducting glass particles, possibility to deposit electroless Ag over the glass was reported to be feasible and efficient [92]. Electroless Ag was deposited on calcite and was first reported by Srikanth and Jeevanandam [93]. In their report, lower concentration of silver ions (e.g., 0.01 M AgNO 3 ) and shorter deposition times (e.g., 30 min) led to the formation of silver nanoparticles on calcite.…”

Electroless metallic coating is referred as the deposition of a substrate material by the process of chemical or autocatalytic reduction of aqueous metal ions deposited to a substrate material without any external supply of power. Electroless nickel alloys are generally considered synonymous to the word "electroless coating" as ~90% of productions in industries are of this alloy coating. Rest of the electroless metallic coatings includes gold, copper, palladium, cobalt, silver, etc. These electroless metallic coatings (other than electroless nickel coatings) are also one of the vibrant areas in the field of materials properties and surface engineering research. From the year 2000 to till date, nearly 1000 SCI indexed research papers were published on this topic. However, no comprehensive studies about the recent progress on this topic were reported elsewhere so far. In this context, the present chapter aims to give a complete overview on various aspects of the rest of the electroless metallic nanocoatings/layer as a whole. More importance will be on the recent developments of the nanocharacteristics and future scopes.

“…The various deposition methods of silver nanoparticle layers on substrates of many kinds include sputter deposition [15], oblique angle deposition [2], electroless deposition [11], chemical vapor deposition [16], photoinduced deposition [3], galvanic coating [5], chemical reduction [13], pulsed laser deposition [8], and thermal evaporation [7]. Electroless plating has received much attention as an alternative technique to vacuum evaporation for nanoparticle synthesis to nanoscale optics of many kinds [1].…”

A new method for silver electroless deposition on glass substrate was developed based on silver itself as the seed layer. The seed layer was first reduced onto the glass surface by a spin-coated glucose layer. Then the silver thin island-like film was deposited electrolessly upon the seed layer by adding the glucose solution as a reducing agent. The seed layer morphology and the silver film were characterized using field emission scanning electron microscope (FE-SEM) and energy-dispersive X-ray analysis (EDX). This technique is the reduction position controlled (RPC) method of electroless deposition using a single solution composition set. It is an environmentally friendly green method that uses no harmful chemical substances.
