摘要: A broadband white light emission was observed ranging from 450 to 900 nm nominally un-doped γ-Al2O3 nano-powders under 803.5 and 975 laser diode excitations. The has a strong dependence on both the environment pressure pumping power. We spectroscopically characterized this in systematic way by collecting spectra, measuring decay- rise patterns changing parameters such as power, wavelength, temperature pressure.
