报道了低温湿化学法合成的荧光粉的光致发光和化学性质。以异丙醇铝、乙酸钇（III）和乙酸铈（III）为原料，在1，4-丁二醇和聚乙二醇（PEG）的混合溶剂中于300 ℃高压釜中合成了YAG：Ce 3+纳米晶，探讨了PEG表面修饰对荧光增强的作用。我们还讨论了十二烷基磷酸酯表面改性剂对LaPO 4：Ce 3+，Tb 3+纳米晶和ZnS：Mn 2+纳米晶两个体系的PL增强的作用。(c)2006 WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆。
We report photoluminescence (PL) and chemical properties of nanocrystal phosphors synthesized by low-temperature wet chemical processing. YAG:Ce3+ nanocrystals were synthesized from aluminium isopropoxide, yttrium(III) acetate tetrahydrate and cerium(III) acetate monohydrate in the mixed solvent of 1,4-butylene glycol and polyethylene glycol (PEG) in an autoclave at 300 degrees C to discuss roles of PEG surface modification on PL enhancement. We also discuss roles of a lauryl phosphate surface modifier on PL enhancement in two systems of LaPO4:Ce3+,Tb3+ nanocrystals synthesized at 140 degrees C in the autoclave and ZnS:Mn2+ nanocrystals synthesized by a reverse micelle method.
