Abstract Realizing a high color rendering index (CRI) in Ce:LuAG transparent ceramics (TCs) with desired thermal stability is essential to their applications white LEDs/LDs as converters. In this study, based on the scheme of configuring red component by Cr 3+ doping, an efficient spectral regulation was realized Ce,Cr:LuAG TCs. A unilateral shift phenomenon could be observed both photoluminescence (PL) and excitation (PLE) spectra By constructing TC-based LED/LD devices remote mode,...
Achieving high color rendering index (CRI) and luminous stability in single-structured Ce:YAG phosphor ceramics (PCs) is crucial for high-power white light-emitting diodes or laser (LEDs/LDs). However, cyan valley insufficient red component of the emission spectra significantly limit their real applications.

Pleated filter media are widely used in particulate filtration, but the particle deposition and pressure drop during loading remain insufficiently explored. This study visualizes patterns pleated media, along with evolution of effective filtration area (EFA) using simulations. The results indicate that, as volume deposited particles increases, initially grows linearly, this rate increase accelerates continues. characteristics related to pleat ratio. A smaller ratio a initial EFA, leading...
Ultra-high-efficiency filter media ensure high air cleanliness but need periodic replacement due to pressure drop increase. Adding a pre-filter can extend the filtration system’s service lifetime, yet and main-filter matching lacks systematic study. This research explored how different combinations affected two-stage ultra-high-efficiency performance. study focused on five grades (F7–F9, H10, H11) two types of media, fiberglass composite. It was found that F8 had best effect extending...
