Porous GaP

Optimized geometries, formation energy, phonon spectra, electronic band structure, and elastic tensor calculation has ensured the energetically, dynamical and mechanical stability for the sheets. Furthermore, the theoretically found nanosheet series possess an intrinsic wide direct band gap preserving from wurtzite tetragonal-based bonding. This high symmetry wide bandgap semiconductor nanosheet series and their derivatives are expected to have broad applications in photocatalysis, and biomedicine.

This paper reports on the temperature-dependent photoluminescence of porous GaP under the 355-nm excitation. Porous GaP was formed by electrochemical anodization of the (111)-oriented bulk material. Photoluminescence taken from the porous GaP at room temperature shows a narrow green emission band peaking at 550 nm (2.25 eV) and a broad red emission one peaking at 770 nm (1.65 eV).

This paper reports on the photoluminescence of porous GaP prepared by electrochemical anodization of (111)-oriented bulk material. Porous and bulk GaP exhibits green and red photoluminescences, respectively when excited by a 355-nm laser. The photoluminescence intensity of porous GaP is much stronger than that of the bulk sample.
