摘要	Efficient cyan phosphors are needed for filling the cyan cavity in the spectra of phosphor converted white light-emitting diodes (pc-WLEDs). In this paper, we reported a strategy to enhance the emission of cyan BaSi2O2N2:Eu2+ phosphor by adding Ho3+ to promote conversion from Eu3+ to Eu2+. External quantum efficiency reached up to 68.9%, excited by 405 nm, based on the observation of emission intensity decrease of Eu3+ and absorption enhancement of Eu2+ with addition of Ho3+. Using the luminescence-enhanced cyan phosphor, commercial yellow, and red phosphors, full-color WLEDs with high color rendering at various color temperatures were packaged on blue LED chips. A WLED with ultra-high color rendering index (CRI = 98) and high luminous efficiency (95 lm/W) at correlated color temperature of 5112 K was achieved.
