Europium (Eu3+) doped phosphors typically exhibit orange or red emission and are used in lighting and display applications, originating from the 5D0→7F1 and 5D0→7F2 transitions of Eu3+. However, BaLaGaO4: xEu3+ deep‐red phosphor, when excited by near‐ultraviolet light, is mainly 5D0→7F4 transition (703 nm). Meantime, the BaLaGaO4: 0.30Eu3+ exhibits a high I423K/I298K value of 71% and a high quantum yield of 82.54%. Furthermore, the prepared samples are mixed with commercial blue and green phosphors in a certain proportion to make white light‐emitting diodes (WLEDs). The color coordinate of the fabricated WLEDs is (0.3208, 0.3436), with a color rendering index of 91.9 and an R9 value of 73. Based on the unique spectral characteristics of this compound, a prototype device of a deep‐red LED with phosphor conversion is developed, which exhibits color coordinates (0.6294, 0.3581) and a color purity of 96.4%. The conducted germination experiments with plant seeds have provided compelling evidence regarding the considerable positive effects of the deep‐red LEDs on plant growth. These findings further emphasize the highly promising potential application of BaLaGaO4: Eu3+ deep‐red phosphor in WLEDs and plant growth lighting.

“…Eu 3+ doped red phosphors have been extensively studied, such as in silicate, borate, vanadate, phosphate, molybdate, tungstate, organic complexes and other systems. [15][16][17][18][19][20] Considering the luminous efficiency, the number of effective Eu 3+ centers is one of the important inuencing factors. In general, the cross-energy transfer (CET) among Eu 3+ ions increases becomes more serious as the luminescent centers increases (doping concentration increases), leading to the occurrence of concentration quenching effects.…”

“…In addition, silicates are easily available and low cost, widely used in basic research studies. 27–29 In this work, we had prepared a K 2 HfSiO 5 :Eu 2+ phosphor via replacing Zr in K 2 ZrSiO 5 :Eu 2+ with Hf through the solid-state reaction. The highest internal quantum efficiency was nearly about 60% and the thermal stability was greatly improved.…”
