bibechana-4897	Haji-Ali, E	Photo and electroluminescence of porous silicon layers	2012	7	.pdf	application/pdf	3442	180	59	In this article, we report: (1) By shining intense light on the sample during the PSi preparation process, it is possible to form PSi layer on n-type silicon substrates as well; (2) Features of an efficient electrochemical cell for preparation of PSi samples, which is simple to make, but has various useful capabilities; (3) Obtaining PL and EL emissions ranging from dark red to light blue from PSi samples is possible by just changing the preparation parameters during PSi formation process (with no need for post-deposition heat-treatment of samples in boiling water). Table (1) gives the color of the PL emission of the prepared PSi samples under UV illumination. Table (1): Color of PL emission of PSi samples (under UV illumination) prepared on p-type Si and under different anodization times.	cache/bibechana-4897.pdf	txt/bibechana-4897.txt
