The structure of NaCaPO4: Eu phosphor confirmed by using X-ray diffraction pattern and crystal structure of NaCaPO4:Eu phosphor was orthorhombic with space group Pnam (62). The prepared NaCaPO4: Eu phosphor showed excellent luminescence (TL/OSL) responses under β irradiation. The TL glow curves were consists over lapping peaks in temperature range 200-450°C and peak fit software was used for deconvolution of this peak. The peak shape method was employ for calculation of kinetics parameters. The photoluminescence spectra of NaCaPO4: Eu phosphor show emission in red-orange regions under near-UV excitation. This excitation is useful for solid state lighting. The prepared phosphor showed outstanding TL/OSL properties hence this phosphor is suitable candidate for radiation dosimetry.<#LINE#>Antonov-Romanovskii V., Keirum-Marcus I.F., Poroshina M.S., Trapeznikova Z.A.

Proper phase of material was established with X-ray diffraction (XRD) test. Also photoluminescence (PL) study was done with aid of fluorescence spectrophotometers Hitachi F7000 and FLS980 (Edinburgh photonics). In the present work the efficient energy transfer (ET) from Tb3+ ion to Yb3+ ion leading to near infra red emission (NIR) was studied in Y2O3 phosphor. The PL of as-synthesized phosphor shows single sharp emissions at 982 nm and 996 nm corresponding to f-f transitions of Yb3+ activator ions in Y2O3 phosphor at ultra-violet (UV) excitation wavelength of 306 nm. The dominating near IR photons emission at 982 nm from Yb3+ ion obtained when Tb3+ ion excited. Because of the ET from one Tb3+ sensitizer to neighboring Yb3+ activators suppressing emissions from Tb3+ ions. The Y2O3:Tb3+-Yb3+ phosphor can convert each UV photon into NIR photons where solar response of crystalline silicon (c-Si) solar cell is optimum. This makes the as-prepared phosphor as prime candidate for potential application in photovoltaic technology.<#LINE#>Sawala N.S., Koparkar K.A., Bajaj N.S. and Omanwar S.K.

The aim of the present study is to do polarographic determination of paracetamol by calibration method using hydrocloric acid and different maxima suppressors such as fuchsion, methyl red, thymol blue and bromocresol green. According to the Ilkovic equation, with all other factors constant.i d = kC where k is a constant defined by Ilkovic equation. This relation is the foundation of quantitative polarographic analysis. Calibration method has been developed and applied for the determination of paracetamol present in some synthetic as well as medicinal samples using selected maxima suppressor-supporting electrolyte system. Polarograms of all system were recorded on D.C. Recording Polarograph using Omniscribe recorder between 200 to 1300 mV using Rotating Platinum micro Electrode as anode and Saturated Calomel Electrode as cathode. The oxidation of paracetamol at rotating platinum electrode is irreversible. Results obtained with synthetic as well as medicinal samples are in good agreement with the quoted values.
