Utilizing CaCO3, CaF2, SiO2, and TiO2 phosphors as approaches to the improved color uniformity and lumen efficacy of WLEDs
The two elements that are most favorable in the quality evaluation for
phosphor-converted LEDs (pcLEDs) these days are the chromatic
homogeneity and the lumen output. In this study, a thorough research on
enhancing color uniformity and luminous…
