Random lasing behaviour in Al-doped ZnO nanorods
نویسندگان
چکیده
A novel method of doping Aluminum (Al) into zinc oxide (ZnO) nanorods by a simple chemical dip process is evaluated in terms its performance random lasing. The ZnO were synthesized the bath deposition (CBD) at fixed temperature 96 °C for 3 h. then dipped solution concentration. time was varied between 0 s and 80 gradual increase Al % from nanorod array observed with increasing time. Doping aluminum nitrate nonahydrate 40 contributes to lasing lowest threshold value 12.48 mJ/cm2 spectral width 2.12 nm.

Femtosecond laser ablation of ZnO nanorods for two-photon-pumped random lasing and optical data storage
Femtosecond laser ablation based on two-photon absorption was employed to cut ZnO nanorods into uniform ZnO nanoparticles of deep subwavelength size. The fabricated ZnO nanoparticles possess a shorter mean transport length for photons at the emission wavelength and a much smaller scattering cross section at the pump wavelength, leading to highly efficient two-photon-pumped random lasing with a ...

Ce-doped ZnO (ZnO:Ce) nanorods have been prepared through a solvothermal method and the effects of Ce-doping on the structural, optical and electronic properties of ZnO rods were studied. ZnO:Ce rods were characterized by XRD, SEM, TEM, XPS, BET, DRS and Raman spectroscopy. 5% Ce-doped ZnO rods with an average length of 130 nm and a diameter of 23 nm exhibit the highest photocatalytic activity ...
متن کاملNarrowband random lasing in a Bismuth-doped active fiber
Random fiber lasers operating via the Rayleigh scattering (RS) feedback attract now a great deal of attention as they generate a high-quality unidirectional laser beam with the efficiency and performance comparable and even exceeding those of fiber lasers with conventional cavities. Similar to other random lasers, both amplification and random scattering are distributed here along the laser med...
