Origins of heat and luminous saturation in LuAG:Ce thin films for high-power laser lighting

Caption

LuAG:Ce thin films synthesized via spray pyrolysis demonstrate how heat generation from the Stokes shift limits luminous performance under high-power laser excitation. Water cooling reduces local temperature by 42.3 °C, raising the saturation threshold and boosting luminous flux by 19.8% to 1938.6 lm, revealing thermal management as the key to unlocking next-generation solid-state lighting performance.
