Optical cavity properties of selectively grown ZnS pyramidal structures were studied. The resonance wavelengths were shifted with the pyramidal size, and pyramidal size dependence of the resonance wavelength was reasonably interpreted by an approximate calculation. Luminescence properties of the ZnS pyramidal photonic dot structures with embedded CdS active layers were studied and a clear modulation of the spontaneous emission was observed at room temperature. Modulated luminescence peaks showed very little temperature dependence of their peaks and their half‐line width, which was 2.1 × 10 —4 nm/K and about 4.4 × 10 —3 meV/K, respectively. These properties will demonstrate the possibility of the future application to the temperature‐stabilized light emitters with pyramidal photonic dot structures.
