Dear research scholars, I m waiting for your response ,I want to know that what should be the min or max values of lambda max and absorbance reported for the Ni,Co and Fe metal during various articles? Because When I m preparing these NP's I observed (through uv-visible spectrophotometer)lambda max 206 to 220 during chemical reduction technique by various conc. Of samples ,using uv-visible spectrophotometer ,is I m correct? I m using chlorides and nitrates salts of metals with various reductions such as hydrazine and sodium borohydrides etc .kindly tell me What are the parameters which shows that the experimental results are correct , any friend can gauid me? Give me some tips of optimization procedure also.
Hello dear, is possible that in your system, there is a metal complex. The absorption value (wave length) of a complex is different than that of the metal alone.
Dear Adwin, transition metals complexes are usually coloured hence their absorption band must be in a visible region (400-800nm ) i think. I just wanna confirm that may be the NP's are very small range 1to 40 nm,giving such peak.
Dear Yuri Mirgorod and dear Astro karthik,I m waiting for your response.
