Abstract EN
Luminescent porous silicon (Psi) fabricated by simple chemical etching technique in different organic solvents was studied.
By quantifying the silicon wafer piece, optical properties of the Psi in solutions were investigated.
Observation shows that no photoluminescence light of Psi in all solvents is emitted.
Morphology of Psi in different solvents indicates that the structure and distribution of Psi are differently observed.
Particles are uniformly dispersive with the sizes around more or less 5–8 nm.
The crystallographic plane and high crystalline nature of Psi is observed by selected area diffraction (SED) and XRD.
Electronic properties of Psi in solutions are influenced due to the variation of quantity of wafer and nature of solvent.
Influence in band gaps of Psi calculated by Tauc’s method is obtained due to change of absorption edge of Psi in solvents.
PL intensities are observed to be depending on quantity of silicon wafer, etched cross-section area on wafer surface.
Effects on emission peaks and bands of Psi under temperature annealing are observed.
The spontaneous signals of Psi measured under high power Pico second laser 355 nm source are significant, influenced by the nature of solvent, pumped energy, and quantity of Si wafer piece used in etching process.
