将四种敏化阴离子萘-1,5-二磺酸盐（15-NDS）、萘-2,6-二羧酸盐（26-NDC）、苯甲酸盐（BA）和对苯二甲酸盐（TA）插入Eu3+掺杂的Zn/Al层状双氢氧化物中。羧酸根阴离子对Eu3+红色发光的增强作用比磺酸根阴离子强得多，降序为TA > 26-NDC > BA > 15-NDS。
Four sensitising anions naphthalene-1,5-disulfonate (15-NDS), naphthalene-2,6-dicarboxylate (26-NDC), benzoate (BA) and terephthalate (TA) were intercalated into a Eu3+-doped Zn/Al layered double hydroxide. The carboxylate anions enhanced the red luminescence of Eu3+ much more strongly than the sulfonate, in the descending order TA > 26-NDC > BA > 15-NDS.
