Phase transition of LaCrO3 and doped-LaCrO3 was studied by DSC, TG and XRD, and thermal expansion during the transition was analyzed. It is found that phase tra
Ce^3+ or/and Tb^3+ doped GdMgB5O10 phosphors were prepared by sol-gel technique. XRD, SEM and PL (photolumineseent) measurements were used to characterize the p
Fast-neutron irradiated nitrogen-doped Czochralski silicon (NCZ-Si) was annealed at 1100 ℃ for different time, then FTIR and optical microscope were used to st
Novel Er3+-doped bismuth lead strontiam glass was fabricated and characterized, and the absorption spectrum and upconversion spectrum of the glass were studied.
