A novel Na₃La(PO₄)₂/LaPO₄:Eu blue-red dual-emitting phosphor with high thermal stability for plant growth lighting

Abstract

The thermal stability of Na3La(PO4)2:Eu phosphors can be enhanced by Li ion doping due to crystal defects.

Highly efficient red-emitting Ca2YSbO6:Eu3+ double perovskite phosphors for warm WLEDs

“…It can be clearly seen that the experimental data is consistent with the tting curve with the slope of À0.1838. Thus, DE is determined to be approximately 0.1838 eV, higher than some previous reports for red phosphors, such as Na 3 -La 2 (PO 4 ) 3 :0.02Eu 3+ (0.0718 eV), 35 or BaZrGe 3 O 9 :Eu 3+ (0.175 eV). 23 This relatively high DE demonstrates that the as-prepared phosphors have good thermal stability, further conrming that the red-emitting phosphor has potential application in LED devices.…”

Far‐red‐emitting YAl3(BO3)4:Cr3+ phosphors with excellent thermal stability and high luminescent yield for plant growth LEDs

“…Agricultural production, the propagation of test-tube seedlings and tissue culture require artificial light sources to promote photosynthesis. 1,2 Phosphors-converted LEDs (pc-LEDs) have been intensively explored as indoor plant lighting sources due to their outstanding features such as long lifetime, energy saving, spectral controllability, and high reliability. 3 Two crucial kinds of photoresponsive biological substance in plants are chlorophyll and phytochrome.…”

Engineering cation vacancies to improve the luminescence properties of Ca14Al10Zn6O35: Mn4+ phosphors for LED plant lamp

“…The phosphor‐converted light emitting diodes (pc‐LEDs), as the promising candidates for artificial solid state lighting, are widely applied to the indoor plant cultivation owing to the long service life, high luminous efficiency, low energy consumption and low cost . In pc‐LEDs, a variety of phosphors can be used to adjust the spectra composition so that the integrated spectrum can be overlapped with the absorption bands of several pigments . Normally, the pc‐LEDs for plant growth are combined by the LED chips with far‐red emitting phosphors .…”

“…6 In pc-LEDs, a variety of phosphors can be used to adjust the spectra composition so that the integrated spectrum can be overlapped with the absorption bands of several pigments. 7,8 Normally, the pc-LEDs for plant growth are combined by the LED chips with far-red emitting phosphors. 9 Presently, the Eu 2+ -doped phosphors with red emission are widely studied by many researchers due to the excellent optical properties, including high luminescence efficiencies and thermal stability.…”
