“…For Ho 3+ (5 mol%)‐doped thoria sample, in addition to strong absorption band at 220‐230 nm (due to ligand to metal charge transfer (LMCT) transition), additional absorptions at 361, 418, 454, 483, 538, and 642 nm from the intraconfigurational f‐f transitions of Ho 3+ ‐ion ( 4 I 8 (ground state) to 4 G 9/2 , 5 G 5 , 5 G 6 , 5 F 3 , 5 S 2 (and 5 F 4 ), and 5 F 5 (excited states)) were seen . Similarly, transitions of Er 3+ ‐ions from 4 I 15/2 (ground state) to 4 G 11/2 , 4 F 7/2 , 2 H 11/2 , 4 S 3/2 , 4 F 9/2 , 4 I 9/2 , and 4 I 11/2 (excited states) appeared at 377, 487, 519, 546, 650, 795, and 972 nm in the UV‐visible spectrum of Er 3+ ‐doped thoria sample . Similarly, from the presence of bands at 328, 470, 690, and 792 nm attributable to the transitions, 3 H 6 (ground state) to 1 D 4 , 1 G 4 , 3 F 3 , and 3 H 6 , (excited states), presence of Tm 3+ in the sample was evident .…”

To address the existing gap in the literature of upconversion studies involving thoria, samples of thoria doped with Ho3+‐Yb3+, Er3+‐Yb3+, and Tm3+‐Yb3+ were synthesized following epoxide gel method and were characterized. Fluorite structure of the doped samples was evident for the calcined samples from the corresponding xerogels as noticed in their powder X‐ray diffraction patterns. The presence of a sharp band near 460 cm−1 in the Raman spectra of all these samples supported the results from diffraction experiments. Intraconfigurational f‐f transitions of Ho3+, Er3+, and Tm3+ were present in the UV‐visible absorbance spectra of these samples. Both normal emission and upconversion emission from these samples have been studied. Emissions in all three basic colors were observed in the upconversion emission spectra. Two‐photon process was found to be responsible for the upconversion in these systems. Decay time measurements for these emissions were analyzed. This synthetic process was further extended to determine the extent of dissolution of heavier lanthanides and found that up to 50 mol% of Ho3+, Er3+ and 60 mol% of Tm3+, Yb3+ could be dissolved retaining fluorite structure. Creation of oxygen vacancies for these heavily doped specimens was quite encouraging and it could be useful as solid electrolytes in fuel cells.

“…The damaged lattice structure is partially expanded, resulting in a reduction in the refractive index. 15 A waveguide structure is formed between the barrier layer with the low refractive index and the air on the material surface. By contrast, some crystals induced by ion implantation would cause compaction, resulting in an increase in the refractive index in the implantation region.…”

An ion implanter was used to irradiate protons with a dose of 8 × 10 16 ions∕cm 2 and an energy of 400 keV into a Ce 3+ :GGG crystal. To our knowledge, this is the first time that ion implantation was applied to a Ce 3+ :GGG crystal. The penetration depth was determined by the stopping and range of ions in matter simulation. The prism coupling method was utilized to evaluate the propagation modes in the H + -implanted waveguide. The end-face coupling method and the finite-difference beam propagation were employed for the analysis of the waveguide performance. The refractive index distribution was reconstructed by the reflectivity calculation method. The main significance of the investigation is to confirm the potential of the ion-irradiated Ce 3+ :GGG crystals for fabricating waveguide structures and devices.

“…12 Hence, the refractive index of the material is varied and the waveguide layer of micrometers order is fabricated. 13,14 The IIPT can control many parameters of the waveguide. For a given species of implanted ions and target material, the energy determines the thickness of the waveguide and the dose affects the change in refractive index.…”

In this work, the ridge waveguide was formed by the femtosecond laser ablation with a central wavelength of 0.808 μm and a speed of 50 μm/s on the planar Nd3+‐doped fluorophosphate glass waveguide that was fabricated by the C3+ ion implantation with an energy of 6.0 MeV and a fluence of 1.0×1012 C3+s/mm2. The mechanism of the ion‐implanted waveguide was discussed by the Stopping and Range of Ions in Matter 2013. The cross‐section morphology of the ridge waveguide was captured by an optical microscope. Its mode characteristics were analyzed by the end‐face coupling method. The ridge Nd3+‐doped fluorophosphate glass waveguides have potential as fundamental structures for many optoelectronic devices including waveguide amplifiers and lasers.
