On the impact of the temperature dependency of the phosphor quantum efficiency on correlated color temperature stability in phosphor converted LEDs

However, an improvement of the thermal conductivity of the matrix materials which encapsulate the phosphor particles would have a similar impact, even for phosphors with current state of the art performance. Besides investing in the progress of phosphor materials, research should also focus on novel concepts and materials to enhance the thermal conductivity of color conversion elements in phosphor converted LEDs.
