    摘要： The invention relates to a method of coating red-luminescing phosphor particles with hematite (.alpha.--Fe.sub.2 O.sub.3), whereby first Fe(OH).sub.3 is deposited on the phosphor particles and subsequently converted into .alpha.--Fe.sub.2 O.sub.3 at a raised temperature. A good adhesion of the hematite pigments to the phosphor particles is achieved in that first an aqueous solution of an iron(III) salt and a complexing agent is prepared, in which the complexing agent and its concentration are so chosen that in combination with Fe.sup.3+ ions complex ions are formed which on the one hand do not yet precipitate at a pH-value which is at least 0.5 higher than the value at which the phosphor particles just fail to be chemically attacked anymore, and which are dissociable at a further increase in the pH-value so that Fe(OH).sub.3 is formed, in that subsequently, if the pH-value is not yet high enough, a basic substance is added to the mixture, in that the pH-value is increased to a value which is at least 0.5 below the value at which Fe(OH).sub.3 starts to precipitate and at least 0.5 higher than the value at which the phosphor particles just fail to be chemically attacked anymore, in that subsequently the phosphor particles are added while stirring, in that at any moment, as required, a substance is added which dissociates upon an increase in temperature and which behaves as a base upon dissociation, and in that then the temperature of the suspension is slowly increased, whereby the phosphor particles are coated with Fe(OH).sub.3 through homogeneous precipitation.

    摘要翻译： 本发明涉及一种用赤铁矿（α-Fe 2 O 3）涂覆红色发光荧光体颗粒的方法，其中首先将Fe（OH）3沉积在荧光体颗粒上，随后在升高的温度下转化成α-Fe2O3。 实现了赤铁矿颜料对磷光体颗粒的良好粘合性，首先制备铁（III）盐和络合剂的水溶液，其中络合剂及其浓度选择为与Fe 3+离子结合 形成复合离子，其一方面尚未沉淀，其pH值比荧光体颗粒刚刚不能被化学侵蚀的值高至少0.5，并且其在离子可以进一步增加 pH值使得形成Fe（OH）3，因此，如果pH值还不够高，则向混合物中加入碱性物质，因为pH值增加到 比Fe（OH）3开始沉淀的值低至少0.5以上，并且至少比荧光体粒子不再化学侵蚀的值高0.5，随后在搅拌下加入荧光体颗粒，因此 任何时候 根据需要，加入随着温度升高而离解的物质，并且在解离时表现为碱，然后缓慢升高悬浮液的温度，由此荧光体颗粒用Fe（OH）3涂覆通过 均匀降水
