ChemInform Abstract: Novel Blue‐Emitting NaxCa1‐xAl2‐xSi2+xO8 :Eu2+ (x = 0.34) Phosphor with High Luminescent Efficiency for UV‐Pumped Light‐Emitting Diodes. Issue 1 (3rd January 2013) - Lee, Ga‐yeon
Abstract The new blue‐emitting phosphor Na0.34Ca0.66Al1.66Si2.34 O8:Eu2+ (I) is synthesized by addition of an EtOH solution of Si(OEt)4 to an aqueous solution of NaNO3, EuCl2, Ca(NO3)2, and Al(NO3)3 followed by solvent evaporation (120 °C, 24 h) and firing of the dry powder in a 5%H2/N2 atmosphere (1400 °C, 3 h).
