dc.description.abstractWe report the fabrication of Fabry–Perot microcavity structures with the organic light-emitting material
tris- 8-hydroxyquinoline aluminum Alq3 and derive their optical properties by measuring their photoluminescence
PL and absorption. Silver and a TiO2–SiO2 multilayer were used as metal and dielectric
reflectors, respectively, in a Fabry–Perot microcavity structure. Three types of microcavity were
prepared: type A consisted of air Ag Alq3 Ag glass ; type B, of air dielectric Alq3 dielectric glass ; and
type C, of air Ag Alq3 dielectric glass . A bare Alq3 film of air Alq3 glass had its PL peak near 514 nm,
and its full width at half-maximum FWHM was 80 nm. The broad FWHM of a bare Alq3 film was
reduced to 15–27.5, 7–10.5, and 16–16.6 nm for microcavity types A, B, and C, respectively. Also, we
could control the PL peak of the microcavity structure by changing the spacer thickness, the amount of
phase change on reflection, and the angle of incidence.
