“…Limited by the power of our laser device, 12.41 kW/cm 2 is the highest power density output that can be realized. This value is much higher than the laser-damaged threshold of conventional Y 3 Al 3.5 Ga 1.5 O 12 : Ce 3+ phosphor (3.90 kW/cm 2 ), AlN-YAG: Ce 3+ phosphor (3.96 kW/cm 2 ), AlN-CaAlSiN 3 : Eu 2+ phosphor (10.37 kW/cm 2 ), etc., as summarized in Figure h. − …”

Laser lighting devices, comprising an ultraviolet (UV) laser chip and a phosphor material, have emerged as a highly efficient approach for generating high-brightness light sources. However, the high power density of laser excitation may exacerbate thermal quenching in conventional polycrystalline or amorphous phosphors, leading to luminous saturation and the eventual failure of the device. Here, for the first time, we raise a single-crystal (SCs) material for laser lighting considering the absence of grain boundaries that scatter electrons and phonons, achieving high thermal conductivity (0.81 W m −1 K −1 ) and heat-resistance (575 °C). The SCs products exhibit a high photoluminescence quantum yield (89%) as well as excellent stability toward high-power lasers (>12.41 kW/cm 2 ), superior to all previously reported amorphous or polycrystalline matrices. Finally, the laser lighting device was fabricated by assembling the SC with a UV laser chip (50 mW), and the device can maintain its performance even after continuous operation for 4 h. Double perovskite single crystals doped with Yb 3+ /Er 3+ demonstrated multimodal luminescence with the irradiation of 355 and 980 nm lasers, respectively. This characteristic holds significant promise for applications in spectrally tunable laser lighting and multimodal anticounterfeiting.

“…40,41 However, there are few studies on the green phosphor material itself. Currently, green converters and their luminescence properties are presented in Table S1 (ESI †), 6,[41][42][43][44][45][46][47][48][49][50][51][52][53][54] and the luminescence properties and thermal stability of new green-light materials need to be studied and improved.…”
