The redox state of cerium and elimination defects were synergistically regulated by a protected-annealing treatment in Ce:YAG transparent ceramics.
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. In this work, a series Ce,Mn:Y<sub>3</sub>(Al,Sc)<sub>2</sub>Al<sub>3</sub>O<sub>12</sub> (Ce,Mn:YSAG) PCs were fabricated by vacuum sintering, an efficient spectral regulation was...
A recorded CRI of 84.8 in Ce,(Pr,Mn):YAG TCs for high-power LEDs/LDs was achieved by the synchronous doping Pr<sup>3+</sup> and Mn<sup>2+</sup> ions.
High lumen-density laser lighting has become an advanced technology.
“Heavy atom substitution” was utilized to improve the thermal behaviors of Ce:LuAG transparent ceramics via Sr 2+ /Si 4+ doping, exhibiting high luminous efficiency radiation (261.98 lm W −1 ) and luminance saturation threshold (∼65 mm −2 ).
Ceramic phosphors are widely considered the next-generation phosphor material for white LED/LD lighting, and a wide spectrum is key factor in improving CRI of lighting sources. In this paper, novel, to our knowledge, barcode-structured YAG:Ce/YAG:Ce,Mn ceramic was designed fabricated. The sources with value 73.5 68.9 were obtained under excitation blue LEDs LDs, respectively. Simultaneously, thanks effective supplementary emission from red LD, ceramic-based source reached 81.8 LD excitation....
High-power, high-brightness laser lighting promotes new requirements for light-conversion materials, such as high thermal conductivity, saturation threshold and compact encapsulation. In this paper, we designed fabricated a novel composite structure ceramic including 1.0 × mm2 Al2O3-YAG:Ce φ=16.0 mm transparent YAG the transmissive configuration in lighting. When pumped by blue from 0∼60 W mm2, all samples exhibited no luminous phenomenon, 10.0 wt.%Al2O3-YAG:Ce/YAG with thickness of 0.3...
Abstract Transition‐metal Mn 2+ ion‐doped transparent ceramics (TCs) are promising color‐convertors to improve color rendition for solid‐state lighting. However, the stabilization of remains a challenge owing changeable atmosphere in specific preparation TC. In this work, variations valence states ions typical garnet lattice host (YAG and LuAG) throughout TC fabrication were demonstrated. By combined first principles calculation experimental investigation, an enhanced self‐reduction was...
Ce:YAG transparent ceramics have great potential in white LEDs, especially under high power packaging technology, due to their superior thermal performance.
The realization of high front light emission in laser lighting under transmissive modes is heavily constrained by low thermal stability and extraction efficiency color converter materials. Therefore, it necessary to improve the heat dissipation capacity utilization through appropriate microstructural adjustments. In this study, what we believe be a novel laminated structure consisting Al2O3 YAG:Ce was designed fabricated for lighting. Through design, possible change phosphor angle,...
