“…Moreover, it is also an important material in the fi eld of lasers technology. Nd 3+ -doped materials are one of the most versatile laser host materials 11 . Similarly like Eu 3+ or Tb 3+ , incorporation of Nd 3+ ions results in the increase of TiO 2 photocatalytic activity due to a higher number of energy levels which can take part in energy transfer mechanism.…”

In this work photocatalytic properties of TiO 2 thin fi lms doped with 8.51 at. % of Nd were described. The self-cleaning phenomenon of thin fi lms was discussed together with the structural, optical and surface properties of prepared thin fi lms. Transparent coatings based on titanium dioxide were manufactured by high-energy reactive magnetron sputtering process. Incorporation of Nd during sputtering process results in amorphous behavior, without a signifi cant infl uence on transparency and colour as compared to the undoped TiO 2 -rutile matrix. Nevertheless, doping with neodymium doubles the photocatalytic activity of the matrix due to higher quantity of photo-generated charge carriers and more effi cient mechanism of energy transfer.

“…The optical absorption spectra of Ln 3+ ions serve as a basis for understanding their spectroscopic properties [10][11][12][13][14][15]. Intensities of the absorption bands are usually expressed in terms of oscillator strengths ( f ) which are statistically weighted to account for the degeneracy of the initial state and are calculated by using the following formula [15].…”

glasses were prepared with three concentrations (0.1, 1.0 and 2.0 mol%) of Nd 3+ ions and their detailed luminescence properties have been investigated. Absorption spectra for 1.0 mol% of Nd 3+ -doped glasses have been analysed using Judd-Ofelt (JO) theory. The observed bands in absorption spectra from ground to excited states are assigned and analysed with the parameterized free-ion Hamiltonian model. The JO parameters have been used to predict radiative properties for 4 F 3/2 → 4 I J ( J = 15/2, 13/2, 11/2 and 9/2) transitions of Nd 3+ ions in these glasses. The Inokuti-Hirayama model has been applied to the non-exponential behaviour of the decay profiles to investigate the mechanism involved in the energy transfer between the donors and acceptors.

“…The rare earth ions are of great scientific and technological interest because of their emission properties which arise from the 4f-4f transitions in the electronic configurations of these ions [4]. The rare earth ions doped borate crystals and glasses are mostly used as promising materials in display devices, sensors, short wavelength lasers and hole burning high-density memories due to their attractive spectroscopic, luminescent and laser properties [5,6]. Recently, a new disordered borate family with the general chemical formula M 3 R 2 (BO 3 ) 4 (M=Ca, Sr, Ba; R=Y, La, Gd) have attracted a great attention.…”

In this paper, we report pure and 5 mol% Nd doped Ca 3 La 2 (BO 3 ) 4 glasses and their spectroscopic properties. A ternary system La 2 O-3CaO-4H 3 BO 3 was adopted and glasses were prepared by using a conventional melt quenching technique. The amorphous nature of the glasses has been confirmed by powder X-ray diffraction analysis. In order to study the spectroscopic properties of fabricated glasses, ultraviolet-visible transmission and absorption spectroscopy has been performed. The absorption spectrum of Nd doped glass shows that the transition 4 I 9/2 4 G 5/2 2 G 7/2 is more intense as compared to the other transitions. Optical band gap energies of both glasses have been determined and found decreased for Nd doped glass as compare to pure glass.
