This work reports the synthesis and characterization of the novel [Dy2(dcpz)2(suc)(H2O)8](H2O)1.5 (dcpz = 3,5-dicarboxypyrazolate, suc = succinate). The structure should probably consist of a binuclear species in which Dy3+ ions are linked by two different bridging organic ligands. Luminescent studies were carried out and revealed that the Dy3+complex exhibits a near white emission under UV excitation.

The novel Y2O3 nanoflowers were synthesized through a facile hydrothermal method without using any catalyst or template. The phase composition and the microstructure of as-prepared products were characterized by field emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD) as well as Fourier transform infrared spectrum. The formation mechanism for the Y2O3 flowers has been proposed.

In this paper, the novel ZnO nanophosphors is synthesized by solgel method. The study exposed ZnO nanophosphors samples in Gamma (y) radiation to investigate their thermo-luminescence (TL) intensity as a function of temperature. The thermo-luminescence response has been studied in the dose range 0.291.16 kGy and it is observed that the thermo-luminescence response increases with increase in the dose. Moreover, the TL intensity increases with temperature and attains its maximum value near 200 Cand decreases after this temperature. Keywords: Dosimetry; Thermo-luminescence; Zinc oxide; Nanophosphors.
