Synthesis and Performance of La₃Si₆N₁₁∶Ce³⁺ Phosphor-in-glass Films for Laser Lighting Applications

Thermally robust Al2O3–La3Si6N11:Ce3+ composite phosphor-in-glass (PiG) films for high-power and high-brightness laser-driven lighting

“…7–9 In this sense, thermally robust color converters are thus urgently required for laser lighting. A variety of phosphor ceramics, 10–13 luminescent single crystals, 14,15 phosphor-in-glass bulks (PiGs) 16–19 and PiG films 20–25 have been investigated as color converters for use in laser illumination. Among these luminescent materials, both phosphor ceramics and single crystals need to be prepared at high temperatures with subsequent complex processing ( e.g.…”

High color rendering and high-luminance laser lighting using all inorganic nitride phosphor films

“…[36][37][38][39] Among them, the CRI value for Ce:GdYAG is slightly better than the other two candidates. 40 In the meantime, the yellow phosphor LSN:Ce that exhibits a wide spectral emission peak has a CRI value of just 74.9 aer being encapsulated as a PiG-F. 41 It is extremely difficult to obtain a high CRI value based on just a single phosphor under laser light illumination.…”

Design of a Novel La3Si6N11:Ce3+ Phosphor-in-Glass Film for High Power Laser Lighting: Luminous Efficiency toward 200 lmW–1

“…In 2021, Zhu et al prepared an LSN fluorescent glass film on the same sapphire coating structure. The CRI can reach 74.9, and CCT is 6422 K; but LE only reaches 157.6 lmW –1 . In 2022, our research group prepared a series of LSN PiG samples, which can realize an LE of 145.91 lmW –1 under blue light excitation of 2.83 W/mm 2 , and the CRI can achieve 73 .…”
