P.59: New Synthesis of Novel Phosphor for LED Technology: Synthesizing Sr₃Y₂(BO₃)₄:Eu²⁺ From Strontium Borate Precursors

Abstract

Doping Eu2+ is challenging in some materials because of the stability of Eu3+. An alternative method for doping divalent europium was explored in the phosphor Sr3B2O6:Eu. Sr3B2O6:Eu has been synthesized with a mixture of divalent and trivalent emission. Here, samples prepared by traditional‐methods are compared to samples prepared using a SrB4O7:Eu precursor.

Unusual red luminescence and super thermal stability of a new narrow-band emission phosphor for backlight display application

“…It is worth noting that Eu 2+ -doped borate oxides emit blue light in general, for example, SrB 4 O 7 :Eu 2+ , 36 Sr 2 B 2 O 5 :Eu 2+ , 37 NaBaB 9 O 15 :Eu 2+ , 38 Sr 3 Y 2 (BO 3 ) 4 :Eu 2+ , 39 Ba 2 Ca(BO 3 ) 2 :Eu 2+ , 40 and SrAl 2 B 2 O 7 :Eu 2+ . 41 However, CBO:Eu 2+ does not exhibit the conventional luminescence of Eu 2+ phosphors.…”
