Red Emitting Phosphor

Abstract This work presents and disentangles the temperature dependent optical properties of the red-emitting phosphor Na3GaF6:Mn4+. Moreover, crystal field and Racah parameters were investigated. It was proven that the material is suitable for the application in warm white LEDs due to its high quantum yield of about 83%, little thermal quenching of the photoluminescence up to 410 K, high lumen equivalent of about 220 lm/W, and strong absorption at 450 nm. In addition, different DFT approaches were used to investigate its band structure. The calculated data were compared to those obtained experimentally. Red phosphor spectra were calculated to evaluate the suitability of red line-emitting phosphors for the application in warm white emitting pcLEDs. Finally, warm white emitting LEDs comprising Na3GaF6:Mn4+ were constructed in order to show the potential of Na3GaF6:Mn4+ serving as a red component in phosphor blends for future warm white pcLEDs.

Red Emitting Phosphor

Ca9Y(PO4)7:Sm3+ phosphor was prepared via solid state reaction. The crystal structure of the phosphor was characterized by X-ray powder diffraction (XRD). The photoluminescence (PL) properties of Ca9Y(PO4)7:Sm3+ were investigated. The emission of the Ca9Y(PO4)7:Sm3+ phosphor consisted of some sharp emission peaks of Sm3+ centered at 563 nm, 600 nm, and 647 nm. The strongest one is located at 600 nm due to the 4G5/2–6H7/2 transition of Sm3+. The critical distance was calculated to be 10.5 Å. The chromatic properties of the sample Ca9Y(PO4)7:Sm3+ phosphor were located in the orange reddish region. The Ca9Y(PO4)7:Sm3+ phosphor may be potentially used as red phosphor for white light-emitting diodes (WLED).

Multiternary nitride and oxynitride compounds doped with rare earth ions, such as Eu2+ and Ce3+ have been enthusiastically applied as various phosphors to white LED. New red and green phosphors, CaAlSiN3:Eu and Ba3Si6O12N2:Eu, have been successfully synthesized, recently. The red phosphor has intense emission around 650 nm under two different irradiations at 405 and 455 nm from blue- and near UV-LED chips, respectively; while strong emission is observed around 520 nm from the green phosphor. Both phosphors also show small thermal quenching over the temperatures up to 150 °C. In addition, both LaSi3N5:Ce and La3Si8O4N11:Ce in lanthanum silicon nitride and oxynitride were examined as candidates for a blue phosphor in white LED with near UV-LED chip.
