合成了新型环保型蓝色颜料(Li1−xNax)2Cu5(PO4)4(0-≤x≤(0.20))，并对其颜色性能进行了研究。在Li+离子位掺入较大的Na+离子使晶格发生扭曲，严重影响了Cu2+的跃迁吸收性质。在(Li1−xNax)2Cu5(PO4)4系列中，(Li0.90Na0.10)2Cu5(PO4)4在CIEL*a*b*体系中表现出鲜艳的蓝色，蓝度值(−b*)为39.4，高于商品FeI4[FeII(CN)6]3颜料(深蓝，−b*=419.3)。
Novel environmentally friendly blue pigments, (Li1−xNax)2Cu5(PO4)4(0 ≤x≤ 0.20), were synthesized and their color properties were investigated. By doping larger Na+ions into Li+ion sites, the crystal lattice was distorted, which strongly affected thed–dtransition absorption nature of Cu2+. In the series of (Li1−xNax)2Cu5(PO4)4, (Li0.90Na0.10)2Cu5(PO4)4showed a vivid blue hue with a blueness value (−b*) of 39.4 in the CIEL*a*b* system; this value is higher than that of the commercial FeIII4[FeII(CN)6]3pigment (dark blue, −b* = 19.3).
