Rod-shaped LuAG:Ce transparent ceramic enabling ultrahigh forward efficiency for laser lighting in a transmissive mode.

Ceramic phosphors have high thermal conductivity and high thermal stability, showing great potential for use in laser lighting. However, it is difficult to further improve the forward efficiency in transmissive mode because of the arbitrarily emitting ceramic phosphors and light loss by secondary optical components. Here, an effective design of rod-shaped LuAG:Ce transparent ceramics was proposed, and the silicone encapsulated ceramic-based devices could operate stably under 3.

Laminated structural AlO/YAG:Ce composite ceramic phosphor with high front light emission for transmissive laser lighting.

The realization of high front light emission in laser lighting under transmissive modes is heavily constrained by low thermal stability and light extraction efficiency of color converter materials. Therefore, it is necessary to improve the heat dissipation capacity and light utilization efficiency of the color converter through appropriate microstructural adjustments. In this study, what we believe to be a novel laminated structure consisting of AlO and YAG:Ce was designed and fabricated for transmissive laser lighting.

Optoacoustic classification of diabetes mellitus with the synthetic impacts via optimized neural networks.

A highly accurate classification of diabetes mellitus (DM) with the synthetic impacts of several variables is first studied via optoacoustic technology in this work. For this purpose, an optoacoustic measurement apparatus of blood glucose is built, and the optoacoustic signals and peak-peak values for 625 cases of rabbit blood are obtained. The results show that although the single impact of five variables are obtained, the precise classification of DM is limited because of the synthetic impacts.
