    Twenty percent of the energy of the solar spectrum is lost as transmission losses in silicon solar cells. Current optical upconverters can recycle some of these NIR photons only at certain wavelength ranges. Photonic crystals and quantum dots are combined on page 568 by J. Marques-Hueso et al. in order to achieve NIR spectral concentration in the 1470–1580 nm range, which is suitable for absorption of erbium-doped upconverters.

  4. Phosphors: Tuning the Luminescence of Phosphors: Beyond Conventional Chemical Method (Advanced Optical Materials 4/2015) (page 416)

    Physical methods presented by J. Hao and co-workers can tune the luminescence of phosphors. On page 431, the principles of this luminescence tuning and some primary strategies are described. Various applications are highlighted based on different groups of phosphors, including metal ion-doped phosphors, semiconductors, nanomaterials, and stimuli-responsive organic phosphors.

  5. Solid-State Lighting: Photoluminescent Materials for Solid-State Lighting: State of the Art and Future Challenges (Advanced Optical Materials 4/2015) (page 423)

    Jörg Meyer and Frank Tappe

    Article first published online: 21 APR 2015 | DOI: 10.1002/adom.201570023

    On page 424, J. Meyer and F. Tappe discuss the generation of white light from blue LEDs and luminescent materials with respect to currently available phosphors. Here, a rendered volume of a state-of-the-art LED is obtained by X-ray computed tomography (CT), to plan the preparation of microsections for more in-depth analysis. Inset, left to right: brightfield contrast in LM, overlay of luminescence contrast, and backscattered electron energy dispersive X-ray fluorescence mapping. Support by Prof. C. Thomas and T. Ogbazghi for microscopy and CT image acquisition is gratefully acknowledged.
