The <span lang="EN-GB">optimal spectral characteristics and photometric qualities in white-emitting light-emitting diodes (WLEDs) featuring red-emitting LEDs instead of phosphor (pc/R-WLEDs) were determined using the luminescent efficiency (LE) theory.

Abstract A lumen efficiency (LE) simulation model with the Monte Carlo method is introduced to the white-light-emitting diode devices that utilize the red LED (light-emitting diode) dyes instead of red-emitting phosphors (R-WLEDs). By simulating this model, the desirable spectrum-related indices and photometric efficiencies, which are adequate for superior chromatic consistency (or R f &gt; 97), can be accomplished for R-WLEDs under the correlated color temperature (CCT) range of 5000–8000 K. The structure of the R-LED has LEDs in red and blue colors (650 nm and 448 nm) combined with phosphors

High color rendering index performance has been required for phosphor-converted warm-white light-emitting diodes (PC-WWLEDs) in lighting industry. The characteristics of low-temperature fabricated phosphor (yellow: Ce3+:YAG, green: Tb3+:YAG, and red: CaAlClSiN3:Eu2+) doped glass were presented for applications to high color rendering index warm-white-light-emitting diodes. Color coordinates (x, y) = (0.36, 0.29), quantum yield (QY) = 55.6%, color rending index (CRI) = 85.3, and correlated color temperature (CCT) = 3923 K were characterized.

Abstract:
Rare-earth doped crystalline materials are of significant interest for photonic and optoelectronic applications, particularly in phosphor-converted white-light-emitting diodes (pc-WLEDs), which offer high brightness, energy efficiency, compact size, durability, and environmental friendliness. However, pc-WLEDs lack a red color component. To address this, europium-doped niobate-based phosphors were synthesized using a high-temperature solid-state reaction technique at 1300°C[1].
