Electroless Ni

The reaction mechanism between electroless Ni–P and Sn was investigated to understand the effects of Sn on solder reaction-assisted crystallization at low temperatures as well as self-crystallization of Ni–P at high temperatures. Ni3Sn4 starts to form in a solid-state reaction well before Sn melts. Heat of reaction for Ni3Sn4 was measured during the Ni–P and Sn reaction (241.2 J/g). It was found that the solder reaction not only promotes crystallization at low temperatures by forming Ni3P in the P-rich layer but also facilitates self-crystallization of Ni–P by reducing the transformation temperature and heat of crystallization. The presence of Sn reduces the self-crystallization temperature of Ni–P by about 10 °C. The heat of crystallization also decreases with an increased Sn thickness.

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.
