Combustion synthesis and photoluminescence of nanocrystalline Y2O3:Eu phosphors
TL;DR: In this article, a nanoscale Y2O3:Eu phosphors have been prepared by glycine-nitrate solution combustion synthesis, and the particle size of resultant powders is much related to the combustion flame temperature, which can be controlled by adjusting the glycine tonitrate ratio.
Journal ArticleDOI
Site-selective spectra and time-resolved spectra of nanocrystalline Y2O3:Eu
Zhang Weiwei,Zhang Weiwei,Xu Mei,Zhang Wei-Ping,Zhang Wei-Ping,Yin Min,Qi Ze-Ming,Xia Shang-Da,Claudine Garapon +8 more
TL;DR: In this paper, the authors showed that the emission bands are from the amorphous phase in nanoscale Y2O3:Eu samples and that the novel emission bands centered at 613 and 622 nm with a lifetime of 0.4 ms emerge in nanoscalibrated X-ray absorption fine structure analysis.
Journal ArticleDOI
Stability, electronic and magnetic properties, and reactivity of icosahedral MCo12 clusters.
TL;DR: The calculated results show that all the clusters have metallic character, and that the clusters with M being Ti, Mn, or Co have closed electronic shells while the others have open electronic shells and are expected to distort further.
Journal ArticleDOI
Theoretical analysis and intensity calculation for the f → d absorption spectrum of U3+ in the LiY F4 crystal
TL;DR: In this paper, the 5f 3 → 5f 2 6d absorption spectrum of U 3+ in LiYF4 has been well calculated using the model proposed by Reid for calculations of 4f N −1 5d spectra.
Journal ArticleDOI
Unit cell group analysis of rare earth elpasolites
TL;DR: In this paper, the 10 unit cell group vibrational frequencies of rare earth elpasolites with general formula M 2 ALnX 6 (M=Cs, Rb; A=K, Na, Li; Ln=lanthanide element or yttrium; X=I, Br, Cl, F) have been determined from Raman spectroscopy and electronic absorption and emission spectra, at temperatures down to 10 k.
