<正> 更准确地说是在莹光体粒子表面附着颜料粒子的绿色发光萤光体。如要提高电视的彩色阴极射线管的对比度,可使用在萤光体粒子表面附着与发光色同色的颜料粒子。这样,附着的颜料粒子起色过滤器作用而使发光的色纯度提高。 相似文献

The last few decades have seen significant developments in the use of heterocyclic compounds in dyestuff and pigment chemistry. The design of newer heterocyclic systems has been a major target area and has focused on economically viable synthesis, absence of effluent problems and freedom from carcinogenic and mutagenic effects. The present article reviews the chemical and patent literature on the chromophoric potential of the 4(3 H )-quinazolinone ring system, including dyes, pigments, fluorescent brightening agents, luminescent inks, electroluminescent devices, photographic couplers, colour formers and photographic fog inhibitors. 相似文献

In the present study, ZnS–Mn nano-luminescent pigments were synthesized, using co-precipitation method. Polyvinylpyrrolidine (PVP) surface modifier and Mn dopant concentrations were considered as affecting parameters. The luminescent ink was loaded with two different concentrations of pigments. The obtained ink was silk-screened on different types of fabrics mainly treated cotton, cotton and nylon. Structure, microstructure, luminescent properties of nano-pigments, inks and fabrics and also rheological properties of the inks were investigated. The results showed that the ceramic ink prepared with nano-luminescent pigment had high photoluminescence (PL) intensity. Moreover, the optimum concentrations of Mn and PVP for obtaining maximum PL intensity were found as 2 and 5 wt%, respectively. SEM images of fabrics indicated that nanoparticles were loaded, nonuniformly, on the fibers. The treated linen and nylon fabrics showed maximum and minimum PL intensity, respectively, due to ink penetration depth in the fabrics. Furthermore, washing fastness estimated for all fabrics was in the proper range. 相似文献
