“…3,17 These include: spraying from the melt, spray drying, thermal plasma, the use of fluxes, laser melt, as well as precipitation. 3,17 These include: spraying from the melt, spray drying, thermal plasma, the use of fluxes, laser melt, as well as precipitation.…”

Low-voltage cathodoluminescent red emitting phosphors for field emission displays

“…300 nm) were prepared by previously reported methods [2][3][4]. Their morphologies and sizes are similar to those in Fig.…”

“…x (where x ¼ 0.2-5 Â 10 À7 ) can be controlled [1][2][3][4][5][6][7][8][9][10][11]. We have reported their suitability as lowvoltage cathodoluminescent (CL) phosphors for FED applications for voltage regimes from 400 to 1500 V and shown their performance is comparable to commercial CRT powders [3].…”

4.3: A Novel Synthesis of Y2O3: Eu Phosphor Using Carbon Dioxide and Ammonia for High Definition CRT and FED Applications

“…Such materials would result in enhanced cathodoluminescence (CL), better packing possibilities on the screen, for high definition applications and low voltage applications for use in field emissive displays (FED) and flat panel displays (FPD). [1][2][3][4][5][6][7][8] Europium-doped yttrium oxide phosphor powders have been used extensively as the red component in cathode ray tubes (CRT) and in fluorescent light tubes. The morphology of the phosphor particles was not considered until recently has not been of great importance.…”

“…2 The use of precipitation methods in the preparation of ceramic powders, has met the stringent requirements on the properties of these ceramic components, namely uniform microcrystalline structures of defined morphology, chemistry and size. [3][4][5][6][7][8] However, such methods should also be uncomplicated, easily reproducible thus, making the commercial production of these phosphors economically viable.…”
