A metallacrown complex has the formula: Ln(III)[12-MC-4]2[24-MC-8], wherein MC is a metallacrown macrocycle with a repeating sub-unit consisting of a transition metal (M(II)) and a hydroxamic acid (HA) ligand that produces a ligand-based charge transfer state when incorporated into the metallacrown complex. In an example of a method for making the metallacrown complex, a hydroxamic acid (HA) ligand that is to produce a ligand-based charge transfer state when incorporated into the metallacrown complex, a transition metal salt, and a rare-earth salt are dissolved in a solvent to form a solution. A base is added to the solution. The solution is stirred at a predetermined temperature for a predetermined time. The solution is exposed to a purification method to produce crystals of the metallacrown complex. 一种金属冠醚配合物具有以下通式：Ln(III)[12-MC-4]2[24-MC-8]，其中，MC是具有由过渡金属(M(II))和异羟肟酸(HA)配体组成的重复亚单元的金属冠醚大环，异羟肟酸配体在并入到金属冠醚配合物中后产生基于配体的电荷转移态。在制备金属冠醚配合物的方法的实例中，将在并入到金属冠醚配合物中后产生基于配体的电荷转移态的异羟肟酸(HA)配体、过渡金属盐和稀土盐溶解在溶剂中以形成溶液。将碱添加到该溶液。在预定
