Laser light illuminant based on YAG: Ce phosphor ceramic with ultra-high luminance, stable output, and excellent heat dissipation
A hundred-watt level blue collimated laser is used to excite YAG: Ce phosphor ceramics to prepare a high-power white laser-based illuminant. A composite ceramic cooling device is prepared to reduce the operating temperature of YAG: Ce phosphor ceramics by using nano-silver to weld ceramics onto a copper block with a water-cooling device. Phosphor ceramics encapsulated with the above device can withstand the excitation of a 123 W blue laser, and its output luminous flux value reaches 14600 lm. The stable output time of the laser-based illuminant is over 30 min, and the operating temperature of the phosphor ceramic surface is only 270 °C. Compared with the non-cooling device package, the luminous flux of the laser-based illuminant composed of phosphor ceramics packaged with the above structure is increased by 252.8 %. The experimental results show that the composite ceramic cooling device can effectively reduce the operating temperature of phosphor ceramics which is an effective way to realize white laser-based illuminants over 10000 lm.
期刊介绍：
Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials.
OPTICAL MATERIALS focuses on:
• Optical Properties of Material Systems;
• The Materials Aspects of Optical Phenomena;
• The Materials Aspects of Devices and Applications.
Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
