TL;DR: In this paper, the authors designed a composite Al2O3-YAG:Ce phosphor ceramic with a unique composite structure, where yellow-emitting YAG-Ce particles are embedded in a non-luminescent Al 2O3 matrix having high thermal conductivity.
Abstract: Solid state laser lighting is a newly emerging technology that combines a blue laser diode (LD) with a yellow-emitting phosphor converter to generate high-brightness white light. Due to high flux irradiation as well as thermal attack from the incident laser, this technology draws a demanding requirement on the thermal performance of the color converter. In this work, we design a Al2O3–YAG:Ce phosphor ceramic with a unique composite structure, where yellow-emitting YAG:Ce particles are embedded in a non-luminescent Al2O3 matrix having high thermal conductivity. The large YAG:Ce particles (5–20 μm) show good crystallinity and a high external quantum efficiency of 76% (upon 460 nm excitation) while the fine Al2O3 grains (0.5–2 μm) contribute to the superior in-line transmittance of 55% at 800 nm by minimizing the birefringence related scattering. The phosphor ceramic exhibits a high thermal conductivity of 18.5 W m−1 K−1 and a remarkable improvement in thermal stability (only an 8% reduction at 200 °C). When irradiated under 445 nm blue laser diodes, the phosphor ceramic shows no luminescence saturation even under a high power density of 50 W mm−2, validating its suitability for high-power solid state laser lighting.

TL;DR: Upon near-infrared (NIR) laser irradiation, the gold bellflower GBFs, with strong NIR absorption, showed very strong PA response and an ultrahigh photothermal conversion efficiency (η, ∼74%) among the reported photothermal Conversion agents.
Abstract: We present a novel gold bellflower (GBF) platform with multiple-branched petals, prepared by a liquid–liquid–gas triphase interface system, for photoacoustic imaging (PAI)-guided photothermal therapy (PTT). Upon near-infrared (NIR) laser irradiation, the GBFs, with strong NIR absorption, showed very strong PA response and an ultrahigh photothermal conversion efficiency (η, ∼74%) among the reported photothermal conversion agents. The excellent performance in PAI and PTT is mainly attributed to the unique features of the GBFs: (i) multiple-branched petals with an enhanced local electromagnetic field, (ii) long narrow gaps between adjacent petals that induce a strong plasmonic coupling effect, and (iii) a bell-shaped nanostructure that can effectively amplify the acoustic signals during the acoustic propagation. Besides the notable PTT and an excellent PAI effect, the NIR-absorbing GBFs may also find applications in NIR light-triggered drug delivery, catalysis, surface enhanced Raman scattering, stealth, ant...

TL;DR: In this paper, the mechanism of catalyst deactivation and regeneration was discussed based on the structure-catalytic property relationships. And the authors concluded that during the reaction propane is dehydrogenated to propene by Cr(IV)O4 tetrahedra, which is simultaneously reduced to Cr(III)O6 octahedra.
