“…Generally, Eu 2? -doped phosphors have a broad excitation band that covers emissions from the n-UV chips and a broad emission band that ranges from the blue region to the red region because of the parity-allowed transitions between the 5d and 4f levels [8,9]. In this case, energy transfer from sensitizer Eu 2?…”

“…The white light‐emitting diodes (LEDs) have attracted considerable attention in recent years due to their superior characteristics of lower power consumption, extraordinary luminous efficiency, good reliability, long life span, friendliness to the environment, high brightness, and fast response time . There are two main ways to generate white light.…”

A series of controllable emissions SrWO :Eu and charge-compensated SrWO : Eum3+ (m = 0.01 or 0.20) phosphors was successfully prepared via a simple co-precipitation method. The energy transfer mechanism was studied based on the Huang's theory. A low magnitude of Huang-Rhys factor (10 ) was calculated using phonon sideband spectra. The Judd-Ofelt parameters Ω (λ = 2, 4 and 6) of Eu -activated SrWO doped with charge compensation were obtained. The calculated Commission Internationale de l'Eclairage chromaticity coordinates were found to be about (0.67, 0.33) for SrWO : Eu0.203+ and charge-compensated SrWO : Eu0.203+ phosphors, which coincided with the National Television Standard Committee system standard values for red. A white light emission was obtained under 362 nm excitation. The correlated color temperature was computed by a simple equation to characterize light sources. Thus, warm white light-emitting diodes with higher Ra can be constructed by combining as-prepared high efficiency, low correlated color temperature and high color purity phosphor.
