Low-voltage cathodoluminescent red emitting phosphors for field emission displays

Luminescence properties of red-emitting praseodymium-activated BaTi4O9 phosphor

“…Generally, sulfide phosphor is used in FEDs. However, sulfide phosphors break down and disperse into the vacuum, contaminating the cathode and thus hindering electron emission [1][2][3][4][5]. Recently, titanates with perovskite structures including CaTiO 3 :Pr 3+ and SrTiO 3 :Pr 3+ were investigated as the host matrices for the red phosphor in FED in order to avoid these problems [6][7][8].…”

DFT calculation, electric and luminescent property of titanate solid state electrolytes based red emitting phosphor A 2 La 2 Ti 3 O 10 :Eu 3+ (A = Na, K)

“…In addition, K 2 La 1.0 Eu 1.0 Ti 3 O 10 shows much higher filament saturation current than that of Na 2 La 1.0 Eu 1.0 Ti 3 O 10 . The filament saturation current of present phosphor K 2 La 1.0 Eu 1.0 Ti 3 O 10 is beyond 50 mA, which is much higher than 8.5 mA in conventional red emitting phosphor Y 2 O 3 : Eu 3þ [33]. All above results concluded that Eu 3þ -doped K 2 La 2 Ti 3 O 10 possess an outstanding potential as red emitting phosphor candidate for LEDs and FEDs application.…”

P‐121: Sub‐micrometre Phosphor Preparation for Next Generation Displays

“…Due to their light scattering properties they have advantageous uses compared to their large particle analogues, e.g. when used in thin, transparent films or for high pixel density displays where individual particles can be larger than the desired pixel dimensions [1]. For our thin luminescent films very low phosphor loadings are used where it is advantageous to have as small a particle size as possible, e.g.…”
