Synthesis and photoluminescence of ZnAl2O4:Eu3+ hollow nanophosphors using carbon nanospheres as hard templates.
ZnAl(2)O(4):Eu(3+) hollow nanophosphors have been for the first time prepared by using carbon nanospheres as hard templates. The ZnAl(2)O(4):Eu(3+) hollow nanophosphors were well characterized by means of XRPD, FESEM, TEM, HRTEM, N(2) adsorption and desorption and PL techniques. The N(2) adsorption and desorption data reveal the porous nature of ZnAl(2)O(4):Eu(3+) hollow nanophosphors and high surface area of 195.3 m(2) g(-1). The PL measurement illustrates red-emitting feature of ZnAl(2)O(4):Eu(3+) hollow nanophosphors arising from the characteristic transitions of Eu(3+) from (5)D(0)→(7)F(j) (j=0, 1, 2, 3, and 4). This simple and efficient synthetic strategy could be extended to prepare other series of aluminates nanophosphors with novel hollow structures.
