“…The first step involves chemical synthesis of Er 3+ -doped NaYF 4 / NaLuF 4 core/shell nanocrystals (NCs) and the second step includes the film formation of such NCs by spin-coating on quartz substrates. It has been observed [26] that replacing yttrium by lutetium in the shell allows an easy and homogeneous tuning of the shell thickness around the core. The synthesis of core-shell NCs and the optimization of shells around the core are presented in [23].…”

Upconversion of sunlight with energy below the band gap of a solar cell is a promising technique for enhancing the cell efficiency, simply by utilizing a larger part of the solar spectrum. The present topical review addresses this concept and discusses the material properties needed for an efficient upconversion process with focus on both silicon and organic solar cells. To design efficient upconverters, insight into topics such as quantum-optics, nano-optics, numerical modeling, optimization, material fabrication, and material characterization is paramount, and the necessary concepts are introduced throughout the review. Upconversion modeling is done using rate equations, while optical modeling is done by solving Maxwell's equations using the finite element method. Topology optimization is introduced and used to generate geometries of gold nanoparticles capable of greatly enhancing the upconversion yield. Fabrication and experimental characterization methods are discussed. Some recent results are presented and finally the possibility of designing upconverting materials capable of increasing the short-circuit current in a solar cell is discussed.

Differential cross sections for single ionization of Li in collisions with fast protons andO8+ions

2014

We study the process of single ionization of Li in collisions with H + and O 8+ projectile ions at 6MeV and 1.5-MeV/amu impact energies, respectively. Using the frameworks of the independentelectron model and the impact parameter picture, fully (FDCS) and doubly (DDCS) differential cross sections are evaluated in the continuum distorted-wave with eikonal initial-state approxima- respectively. For O 8+ impact inclusion of the heavy particle (NN) interaction in the calculations is crucial and effects of polarization due to the presence of the projectile ion have also to be taken into account for getting very good agreement with the measured data. Our calculation reproduces the satellite peak structure seen in the FDCS for the Li(2s) measurement, which we explain as being formed by a combination of the binary and NN interactions.

“…The sudden decrease of DDCSs at around η = 2 a.u. at small electron energies seen in [6] is now deemed to be an artifact caused by the limited experimental momentum acceptance [18]. Therefore, we have removed the three experimental points for E e = 2 and 10 eV for the highest transverse momentum transfer (cf.…”

Doubly-differential-cross-section calculations forK-shell-vacancy production in lithium by fastO8+-ion impact

Inner-shell vacancy production for the O 8+ -Li collision system at 1.5 MeV/amu is studied theoretically. The theory combines single-electron amplitudes for each electron in the system to extract multielectron information about the collision process. Doubly differential cross sections obtained in this way are then compared with the recent experimental data by A. C. LaForge et al. [J. Phys. B 46, 031001 (2013)], yielding good resemblance, especially for low outgoing electron energy. A careful analysis of the processes that contribute to inner-shell vacancy production shows that the improvement of the results as compared to single-active-electron calculations can be attributed to the leading role of two-electron excitation-ionization processes.
