Sg. Romanov et al., THE EFFECT OF THE PHOTONIC STOP-BAND UPON THE PHOTOLUMINESCENCE OF CDS IN OPAL, Physica status solidi. a, Applied research, 164(1), 1997, pp. 169-173
Photonic bandgap (PGB) structures based on synthetic opal have been mo
dified by in-situ growth of CdS. The resulting structures show an enha
nced stop-band as determined from transmission and reflection measurem
ents. Photoluminescence from the structures is squeezed to the low-ene
rgy side of the stop-band, with the effect increasing with higher frac
tion of CdS.
