Wide-band excited LaBMoO6:Eu3+ red phosphor for white-light-emitting diode

Thermal and pump power effect in SrMoO4:Er3+-Yb3+ phosphor for thermometry and optical heating

“…The research in the field of REs doped phosphors has been growing due to their various technological applications such as in light emitting diodes (LEDs), display devices, optical temperature sensing, nanoheating and solar cell efficiency enhancement [1][2][3][4][5]. In recent years, frequency upconversion (UC) phenomenon has become an effective way of producing visible light by using near infrared (NIR) diode laser excitation [6][7][8].…”

Novel high-efficiency Eu3+-activated Na2Gd2B2O7 red-emitting phosphors with high color purity

“…[22][23][24][25][26][27][28] Eu 3+ ions show two prominent characteristic emission peaks in the orange-red and pure red regions due to the 5 D 0 / 7 F 1 and 5 D 0 / 7 F 2 intra-congurational transitions, respectively. 29 In addition, the phosphor emission is strongly correlated to chemical surroundings around the crystallographic site. As seen from the literature, Eu 3+ ion-activated phosphor emits two distinct colors, which are induced from magnetic-dipole transition ( 5 D 0 / 7 F 1 ) and electric-dipole transition ( 5 D 0 / 7 F 2 ).…”

Facile synthesis and optical properties of Ce:YAG polycrystalline ceramics with different SiO2content

“…Nowadays, white light-emitting diodes (WLED), which are regarded as a next-generation solid-state lighting source, have attracted considerable attention due to their excellent merits in many aspects such as long lifetime, high energy efficiency, environmental advantages and so on. [1][2][3][4][5][6] The current leading commercial WLED combines an InGaN blue-emitting chip with a Ce:YAG yellow-emitting phosphor packed on the chip surface using an epoxy resin or silicone [7][8][9][10] because of the lower manufacturing costs at present and the capability to promote a high light yield. A portion of the blue light is absorbed by phosphor and reemitted as yellow light; the remainder is transmitted.…”
