The Relationship

CaMoO4: Eu3+ red phosphors were synthesized by co-precipitation method with H3BO3 as an additive and the relationship between H3BO3 doping amount and luminescent properties were studied. The brightness increased with increasing H3BO3 amount, the brightness of the CaMoO4: Eu3+ powder with 10 mol％ H3BO3 was 3.2 times higher than that of the phosphor without H3BO3.

A series of oxonitridosilicates phosphors Ba - Si x - O - N / Eu 2+ ( x = Si / Ba =1~8, 5atom% Eu 2+) were synthesized using traditional solid-state reaction. For x = 2~8, the main phase of the obtained samples was Ba 3 Si 6 O 12 N 2. All Ba - Si x - O - N / Eu 2+( x = 1~8) materials could be efficiently excited in the UV to visible region(310~450 nm ) and had a green emission at 508~522 nm , making them attractive as conversion phosphors for white LED applications. With increasing x values, the emission peaks shifted to the longer wavelength region, while the emission intensity had a maximum at x = 6. The influence of the firing times was also discussed, after twice fired, there was a tendency of single-phased formed of the obtained materials and the emission intensity was greatly improved.
