A novel blue-emitting phosphors (CsBaYB6O12:Ce3+): Potential applications in w-LEDs and X-ray phosphors

Intensity enhancement of photoluminescence in Tb3+/Eu3+ co‐doped Ca14Zn6Al10O35 phosphor for WLEDs

“…[2][3][4][5][6] At present, white light emitting diodes (WLEDs) have become the conventional lighting source in different fields because of their advantages. [7][8][9][10][11][12][13] However, the performance of the available green and blue emitting phosphors is substantially higher than that of the currently utilized Y 2 O 2 S:Eu 3+ red phosphor. [14,15] Moreover, the red phosphor becomes chemically unstable when exposed to ultraviolet (UV) light; As a result, its lifespan is considerably decreased.…”

A broadband yellow-green emitting mixed orthoborate–pyroborate phosphor, Ba2Sc2B4O11:Ce3+, for white light emitting diodes

“…14 Thus, it is very necessary to find new phosphors with broadband blue-green or yellow-green emission suitable for n-UV LED chips. 15,16…”

“…14 Thus, it is very necessary to find new phosphors with broadband blue-green or yellow-green emission suitable for n-UV LED chips. 15,16 Nowadays as one of the key rare Earth ion activators, Ce 3+ typically presents broad excitation and emission bands based on the 4f-5d transition. 17,18 The 4f-5d transition is environmentally sensitive due to the exposed outer shell layer d electrons, so the luminescence properties of Ce 3+ are greatly determined by the host lattice and the versatile emission can be realized in different solids, 19 such as Ca 1.5 Y 1.5 Al 3.5 Si 1.5 O 12 :Ce 3+ , 20 LiY 9 (SiO 4 ) 6 O 2 :Ce 3+ , 21 and (La, Ca) 3 Si 6 N 11 :Ce 3+ .…”
