Abstract

Spectra of linear absorption and photoluminescence (PL) at different polarization of the laser excitation; photoluminescence excitation (PLE) spectra and time - resolved PL of the InP quantum wires (QWRs) crystallized in transparent nanotubes of chrysotile asbestos have been measured. We evaluate the exciton ground state binding energy as large as 200 meV. In the presence of the strong resonant laser pumping of InP QWRs (the energy of laser photon coincides with the absorption band of QWRs) the induced suppression and enhancement of PL in different parts of the spectra and the blue shift (about 13meV) of the PL maximum relatively to the energy of laser photon have been observed. The PL features of InP QWRs has been explained by saturation of the capture centers and Auger process.
