Abstract: A long-afterglow phosphor is added to an electroluminescent lamp in order to continue to provide illumination after the electrical power has been removed from the lamp. When the electroluminescent lamp is powered, it emits light caused the stimulation of an electroluminescent phosphor in the electric field. The emitted light further stimulates a long-afterglow phosphor so that when the lamp is turned off, and the electroluminescent phosphor ceases to emit light, the afterglow phosphor continues to provide a visible illumination at a lower intensity for many additional minutes or hours.

Abstract: A method is provided for making narrow-band, UVB-emitting, (Y,Gd,Ce,Pr)Mg borate phosphors. The method involves the use of a mixed oxide co-precipitate which is combined with MgO and boric acid and fired twice to form the borate phosphor. The mixed oxide co-precipitate is formed by dissolving sources of Y, Gd, Ce, and optionally Pr, in an acid solution. Oxalic acid or ammonia is added to the solution (or vice versa) to form a co-precipitate of oxalates or hydroxides that are further fired to obtain a mixed oxide co-precipitate. The use of the mixed oxide co-precipitate improves homogeneity and yields a phosphor having a higher brightness with very little or no sticking between the fired cakes and the firing crucibles.

Abstract: The present invention is a single-component, UV-emitting phosphor having a composition represented by the general formula (Y1?x?y?zLaxGdyCeZ)PO4 where x has a value in a range from 0.001 to 0.98, y has a value in a range from 0 and 0.1, z has a value in a range from 0.01 and 0.2, and x+y+z<1. The phosphor when stimulated by 254 nm radiation emits in both the UVA and UVB regions. The relative balance of the UVA and UVB emissions may be varied by adjusting the relative amounts of Y and La. Brightness can be increased by adding Gd to the composition.

Abstract: A method for forming a SiGe HBT, which combines a SEG and Non-SEG growth, is disclosed. The SiGe base layer is deposited by a Non-SEG method. Then, the first-emitter layer is developed directly upon the SiGe base layer that has a good interface quality between the base-emitter.

It not only reduces the resistance of the SiGe base layer, but also avoids the annealing that may influence the performance of the device.

The oil seed is subjected to a dehulling process to separate out the hull and kernel and the dehulled oil seed is then compressed into flakes under low temperature. The oil seed is then dephenolized and undergo low temperature delintion. In addition, direct hydrolyzation of the oil-complex is carried out. This technology can be used to produce high quality oil and obtain hydrolyzed protein, thereby comprehensively utilizing the oil seed.
