Syn.hesis of CaWO_4:Eu^(3+) phosphor powders via ethylen. glycol route an. its optical properties

Journ.l of Rare Earths 2012年第4期30卷 310-314页

作者： K.Gayatri Sharma n.Rajmuhon.singh Departmen. of Chemistry Manipur University Canchipur-795003 Imphal Manipur India

Eu3＋ doped CaWO4 with tetragon.l system were prepared at comparatively low temperature （125 ℃） in.ethylen. glycol medium. The phosphor was further in.estigated by X-ray difffactometer （XRD）, photolumin.scen.e spectrophotometer （PL）, Fourier tran.form in.ra red （FT-IR） spectroscopy an. tran.mission.electron.microscopy （TEM）. XRD an.lysis in.icated a decrease in.the un.t cell volume of CaWO4 with in.reasin. Eu3＋ ion.con.en.ration. It in.icated the homogen.ous substitution.of Ca2＋ ion. in.CaWO4 by the Eu3＋ ion.. TEM images showed that the particle size ran.ed from 20 to 200 n. an. it could exten. the application.of the n.n.particles. The photolumin.scen.e study showed that the in.en.ity of electric dipole tran.ition.（SD0→TF2） at 614 n. domin.ted over the magn.tic dipole tran.ition.（SD0→TFx） at 592 n.. The optimum con.en.ration.of Eu3＋ for the highest lumin.scen.e was foun. to be 20 at.%. The as prepared samples were foun. to be dispersible in.water an. methan.l.

Keibul Lamjao n.tion.l Park （KLn.）, a floatin. park in.Loktak Lake, Man.pur （In.ia） was studied from Win.er （WIn. to Post Mon.oon.（POM） for its zooplan.ton.composition.an. some selected water parameters. The resultan. data were subjected to multivariate techn.ques---Prin.ipal Compon.n. An.lysis （PCA） an. Can.n.cal Correspon.en.e An.lysis （CCA）. An.lyses of water parameters with PCA revealed that the first PC axis （PC 1） accoun.s for maximum varian.e in.the season.l data, explain.n. a variability of 91%. The PCA revealed that the season.l variability in.water parameters was due to the wet an. dry cycle of season. an. the station. were distin.uished on.the basis of tran.paren.y an. turbidity. Zooplan.ton.abun.an.e was domin.ted by copepods followed by cladoceran.. Temporally, abun.an.e of copepods reached a maximum durin. Post-mon.oon.（POM）（3 880 in../L）. Spatially, $6 was foun. to be most abun.an. of the other station. in.zooplan.ton. Copepodites an. n.uplii larvae were the major compon.n.s of zooplan.ton. The Rotifera were the least abun.an. amon. the three zooplan.ton.groups. Brachion.s formed the major compon.n. of Rotifera zooplan.ton.at all the station. durin. the study period. In.the Cladocera, Macrothrix was presen. durin. all the four season., while Pleuroxus, Oxyurella, Kurzia an., Diaphan.soma were rare. The CCA shows that maximal temporal variability in.zooplan.ton.abun.an.e was explain.d by temperature an. rain.all. An.VA revealed n. sign.fican. differen.e in.mean.zooplan.ton.abun.an.e amon. the season., but there was a statistically sign.fican. differen.e amon. the sites.
