“…The assignment of these bands is given in Table I. The Ndx glasses present higher transparency in the UV region when compared to other borate glasses, [19][20][21] with a maximum absorption edge at 240 nm ͑for Nd01͒. This result is consistent with that observed for rare-earth doped YAB crystals, whose absorption edges vary between ϳ200 and 300 nm, depending on the doping level.…”

“…Physical and spectroscopic properties of silicate, borate and phosphate glasses doped with various rare earth (RE 3+ ) ions have been extensively investigated in the past, and many technological and commercial applications have been realized [1][2][3][4]. Neodymium has been most widely studied as doping agent and has come out to be most applicable for laser action, since neodymium lasers can operate with high efficiency, even at room temperature.…”

The effect of increasing the rare earth ion concentration on the physical and spectroscopic properties of Nd 3+ doped sodium-lead-borate glasses have been studied for the compositions (10-x) Na 2 O-30PbO-60B 2 O 3 -xNd 2 O 3 , where x = 1.00, 1.25, 1.50, 1.75 and 2.00 mol %. Optical band gaps, cut-off wavelengths and various spectroscopic parameters (E 1 , E 2 , E 3 , F 2 , F 4 , F 6 and ξ 4 f ) have been determined from the room temperature absorption spectra. Judd-Ofelt theory has been employed to determine the intensity parameters Ω 2 , Ω 4 and Ω 6 which in turn are used to evaluate radiative transition probability (A), branching ratio (β) and radiative lifetime (τ R ) for the fluorescent level 4 F 3/2 . The Ω 2 parameter and hence the non-symmetric component of electric field acting on Nd 3+ ion is found to be highest for glass with 1.75 mol% of Nd 2 O 3 . Because of the poor resolution of hypersensitive transition, the covalency of the Nd-O bond has been characterized by the relative intensity of 4 I 9/2 → 4 F 7/2 , 4 S 3/2 . The highest covalency has been predicted for glass with 2 mol% Nd 2 O 3 . The radiative properties are found to improve with an increase in concentration of Nd 2 O 3 for the present study.

“…More recently, some studies were done to introduce cerium phosphate in the optical field [14,15]. The optical reflection spectrum of CePO4 is affected critically by their crystallization which by turn depends on the method of preparation as well as the calcination temperature [16][17].…”

KEYWORDSCerium phosphate, CePO4, nanoparticles with hexagonal or monoclinic phase was synthesized by the reaction between Ce(SO4)2.4H2O and two different phosphate sources, H3PO4 and Na2HPO4. The obtained gel was dried and calcined at different temperatures (200, 400, and 800 о C). The effects of the precursor materials and the calcination temperatures on the produced phases were studied. Both X-ray diffraction (XRD) and infrared spectroscopy (IR) were used to follow the changes in the phase structure for the produced samples. The thermal behaviour of the as prepared samples was studied by using differential scanning calorimetric (DSC) and thermogravimetric analysis (TGA). The morphology, crystallinity and particle size of the produced samples as prepared and calcinated were characterized by transmission electron microscope (TEM). The analysis of TEM results indicated that CePO4 was prepared in nano-sized particles.Cerium phosphate Synthesis X-ray diffraction IR DSC/TGA TEM
