Abstract

We obtained upconversion (UC) light-emitting photonic materials ( YbPO 4 : Er ) with an inverse opal structure by the self-assembly technique in combination with a solgel method. The effect of the photonic stopband on the UC luminescence of the H 11 / 2 2 , S 3 / 2 4 I 15 / 2 4 , and F 9 / 2 , 4 I 15 / 2 4 transitions of Er 3 + has been observed in the inverse opals of the Er 3 + -doped YbPO 4 . Significant suppression of the UC emission was detected if the photonic bandgap overlapped with the Er 3 + ions emission band, while enhancement of the UC emission occurs if the emission band appears at the edge of the bandgap.
