(CBT)-based Aurivillius high-temperature piezoceramics with different Sb-Mn co-doping amounts were synthesized via the conventional sintering technique. The influences of doping amount on the product were studied via their crystal structure, microstructure, and piezoelectric performance. It is found that an appropriate Sb-Mn co-doping amount can effectively optimize the crystal structure and decrease......
of both Eu2+ and Ce3+. The methods of photoluminescence, thermoluminescence and phosphorescence were used to study the samples, and possible mechanism was suggested. The co-doping of Ce3+ ions poisoned...Long Lasting Phosphorescence in Eu2+ and Ce3+ Co-Doped Strontium Borate Glasses Su Qiang1,Zhang Lan1,Li Chengyu1 (1.Key Laboratory of Rare Earth Chemistry and Physics, Changchun Institute......

The co-doping of Ce3 + ions poisoned the phosphorescence emission of Eu2 + because of the competition to obtain the trapped...Long Lasting Phosphorescence in Eu2+ and Ce3+ Co-Doped Strontium Borate Glasses张岚,李成宇,苏锵摘 要:<正>Long lasting phosphorescence (LLP) was observed in Eu2......
">YBa2Cu3O7-x(YBCO) films with co-doping of Ba Ti O3(BTO) and Y2O3 nanostructures were successfully fabricated on La Al O3(LAO) substrate by metal organic deposition using trifluoroacetates(TFA-MOD). The focus of this study was to optimize the process conditions during the firing heat treatment of high critical current density(J C)-co-doped YBCO films. The effect of the firing temperatures on both......
Investigation on energy transfer from Er3+ to Nd3+ in tellurite glass沈祥,聂秋华,徐铁峰,戴世勋,王训四摘 要:<正>A study of energy transfer of Er3+/Nd3+ codoped tellurite glasses was presented. By Nd3+ co-doping, both the Er3+ green emission corresponding to the Er3+: (4S3/2, 2H11/2)→4I15/2 transitions and the red emission corresponding to the Er3+: 4F9/2→4I15/2......
that thishost was thermally and optically superior for practical applications.Strong emission centered at 1.22 μm was observed in all Tm3+ single-doped,Tm3+/Ho3+ and Tm3+/Er3+ co-doped samples with an excitation of 808 nm wavelength.The emission was attributed to the Tm3+:3H5→3H6 transition.The co-doping of Ho3+ or Er3+ largely broadened the width and slightly strengthened the intensity of the 1.22 μm......
spectra under ultraviolet (200-300 nm) radiation showed a dominant peak at 543 nm attributed to the 5D4→7F5 transition of Tb3+, which was greatly en-hanced by the co-doping of Ce3+, indicating...="ChDivSummary">Tb3+ and Ce3+ co-activated LiZnPO4 phosphors with high luminescence efficiency were synthesized by a high temperature solid-state reaction at 1000 oC for 3 h.

-doped sample was longer than that of the others. Furthermore, the co-doping samples had stronger thermoluminescence (TL) intensity and therefore longer afterglow duration. At last, the self-reduction...="ChDivSummary" name="ChDivSummary">The luminescent properties of Sr2.97MgSi2O8:Eu2+0.01 phosphors were investigated with different Ln3+0.02(Ln3+:Dy3+,Er3+,Ho3+) co-dopants.

and Technology摘 要:A series of K3Gd(PO4)2:Tb3+,Sm3+ phosphors were synthesized through solid state reaction. By co-doping Tb3+ and Sm3+into K3Gd(PO4)2 host and singly varying the doping concentration of Sm3+, tunable colors from green to yellow and then to orange were obtained in K3Gd(PO4)2:Tb3+,Sm3+ phosphors under the excitation at 373 nm. The energy......
