Photoluminescence Tuning of Porous Silicon by Electrochemical Etching in Mixed Electrolytes
We have systematically studied the evolution of the photoluminescence(PL) tuning of porous silicon(PS) by electrochemical etching in various mixed electrolytes. The electrolytes employed as an etchants were mixtures of HF:CH3COOH:HNO3:C2H5OH solutions where the composition ratios (%) were varied from 10:1.98:0:88.02 to 10:1.98:8.4:79.62 under constant concentration of HF and CH3COOH with a tota...
متن کاملStructural and optical properties of n- type porous silicon– effect of etching time
Porous silicon layers have been prepared from n-type silicon wafers of (100) orientation. SEM, FTIR and PL have been used to characterize the morphological and optical properties of porous silicon. The influence of varying etching time in the anodizing solution, on structural and optical properties of porous silicon has been investigated. It is observed that pore size increases with etching tim...

متن کاملStructural and Optical Properties of Gold Nanoparticles Formed by Wet-Chemical Method
Our aim in this work is the synthesis and study optical and structural properties of gold nanoparticles.Gold (III) chloride trihydratewas taken as metal precursor, ascorbic acid at the presence of an appropriate amount of NaOH as reducing agent and polyvinylpyrrolidonek-30 (PVP K-30) as a stabilizing and capping agent. The reaction was performed in high-speed stirring rate at room temperature.S...
