Аннотация: Photonic bandgap effects in reflectance and photoluminescence Of SiO2 opal-based photonic crystal with embedded europium (III) salt of ethylenediaminetetraacetic acid (HEuEDTA) were studied. The position of the bandgap was accurately fitted to the wavelengths of visible lines of Eu3+ photoluminescence by proper choice of the size Of SiO2 spheres. High spatial anisotropy of photoluminescence was observed by spatially- and spectrally-resolved laser spectroscopic measurement. The influence of crystal structure quality on spatial anisotropy of photonic bandgap and photoluminescence is discussed.
