摘要

以层状稀土氢氧化物为原料，在pH值为7和8的条件下，采用可控双射流沉淀法合成了氧化物荧光粉。沉淀后进行水热处理，对发光强度产生不利影响，但提高了层状稀土氢氧化物的结晶度。这使得从这种层状氢氧化物中获得具有更高透明度和均匀性的发光薄膜成为可能。

Study of the effect of hydrothermal processing of yttrium-europium hydroxsonitrate on luminescence intensity of the oxide phosphors

Oxide phosphors were produced from layered rare earth hydroxides synthesized by controlled double-jet precipitation at constant values pH 7 and 8. After precipitation, hydrothermal processing was carried out, which adversely affected luminescence intensity, but increased the crystallinity of the layered rare earth hydroxides. This makes it possible to obtain luminescent films with increased transparency and homogeneity from such layered hydroxides.
