The light-emitting diodes (LEDs) have emerged as a sustainable illumination solution in the lighting industry. However, the commercial LEDs suffer from low chromatic rendition performance. This work proposes a feasible approach to enhance the quality of commercial LED packages via regulating scattering factors. The TiO2 nano scattering particles are added into the YAG:Ce3+ compound to enhance the internal scattering performance, inducing the blue-light conversion and extraction. In this work, TiO2 concentration varies from 0 wt% to 20 wt%. Results show that 5 wt% of TiO2 is the right concentration to achieve the optimal scattering performance for improvements in luminosity and color rendition of the LED. If the TiO2 concentration is beyond 5 wt%, these two parameters decline owing to too intensive light scattering. Meanwhile, 10 wt% is the most appropriate concentration of TiO2 to enhance the color uniformity of the LED.
