无机光致变色材料的分类
光致变色材料,是指受到光源激发后能够发生颜色变化的一类材料。
无机光致变色材料的分类:
一、过渡金属氧化物:这类物质主要有WO3、、MoO3、TiO2等。WO3只氧化钨作为一种重要的无机光致变色材料,具有稳定性好、成本低等优点,但其光致变色效率较低。二、金属卤化物:金属卤化物具有一定的光致变色性.如碘化钙和碘化汞混合晶体、氯化铜、氯化锅、氯化银等。当照射掺有La、Ce、Gd或Tb的氟化钙时,会发生稀土杂质的光谱特征吸收,其变色机理是金属离子变价。如掺Ce的氟化钙晶体会产生晶格缺陷,使无色的Ce3+变为粉红色的缺陷。三、稀土配合物:对稀土配合物光致变色的研究较少。稀土离子与梭酸、邻菲咯琳的水溶液具有可逆的光化学反应,研究了斓系元素一N,N一二(2一氧毗咯一l一甲基)甘氨酸(MPG)一邻菲咯琳(phen)三元配合物体系水溶液的光致变色性质。太阳光或汞灯照射下溶液由黄色转变成绿色,而在避光处保存时,绿色褪去变成黄色溶液。这个体系变色的响应时间和颜色的深浅与光的强度、光照时间以及溶液的pH值有关。光照强度增大,光照时间延长,体系变色快,颜色深。pH值较高时,体系变色深;而pH值较低时,体系几乎不变色;但过高的pH值会导致斓系离子以氢氧化物沉淀的形式析出。有关此三元配合物的变色机理有待进一步的研究。产品供应列表:4-二甲氨基-4'-硝基联苯
