A schematic picture of sample structure and PL measurement.
Normalized PL spectra (solid lines) measured with Arrangement 1 (a) and Arrangement 2 (b). Reflectance spectrum (dotted lines) is also plotted for comparison.
Calculation results of emission from ZnS:Mn layers, except cavity layer (dotted line), and emission from only cavity layer (solid line) in Arrangement 1 (a) and Arrangement 2 (b). In Arrangement 2, background emission (dotted line) is suppressed.
Calculated emission spectra of the one-dimensional PC using the Fano resonance formula. In this case, we consider the interference effect between discrete cavity mode and continuous background mode.
