Comparative study of Al2O3-YAG:Ce composite ceramic and single crystal YAG:Ce phosphors for high-power laser lighting

CaAlSiN3:Eu/glass composite film in reflective configuration: A thermally robust and efficient red-emitting color converter with high saturation threshold for high-power high color rendering laser lighting

“…These favorable properties enable LD-based white-light sources to achieve very high luminance and illuminance; therefore, they have a promising future in applications like searchlights, auto headlamps, projectors, and street lamps. Similar to white LEDs, commercial white LDs are usually made from a blue LD chip and phosphor(s) [4][5][6][7][8]. Thus, phosphors are one of the key components and significantly affect the colorimetric and photometric properties of white LDs.…”

Efficient spectral regulation in Ce:Lu3(Al,Cr)5O12 and Ce:Lu3(Al,Cr)5O12/Ce:Y3Al5O12 transparent ceramics with high color rendering index for high-power white LEDs/LDs

“…Additionally, it has been found that composite structure TCs are promising due to their high saturation threshold and excellent thermal performance. Xu et al [23] found that light homogeneity of Al 2 O 3 -YAG:Ce composite ceramic was far better than that of YAG:Ce single crystal, due to intense scattering by the phase/ crystal boundaries. A high thermal conductivity of 18.5 W/(m•K) and a remarkable thermal stability (only a 8% reduction in emission intensity at 200 ℃ compared with that of room temperature) were realized in Al 2 O 3 -YAG:Ce composite TCs.…”

Growth, Optical, and Laser Properties of Large‐Sized Cr,Nd:Y3Al5O12 Crystal

“…[14][15][16] The comparison of the luminescent properties of single crystal and composite ceramic of Ce:YAG for laser pumped luminescence revealed that single crystal has higher luminescence saturation threshold and luminous efficacy under the same conditions. [17] High-quality Cr,Nd:YAG single crystals may have a better laser performance than ceramics.…”
