Self-assembly of Lanthanide Oxide Photonic Crystals and Its Modification on Spontaneous Emission
摘要
Abstract
The birth of the concept of photonic crystal ( PC ) makes the dream of manipulating photon become reality. Possessing spatial periodicity in their dielectric constant on the length scale of the optical wavelength, PCs behave with electromagnetic waves just like atomic crystals do with electrons. As an electronic band gap is created by the periodic arrangement of atoms in a semiconductor , the periodic electromagnetic modulation created by a PC can yield a photonic stop band ( PSB) , which has significant modification on the spontaneous radiative rate and emission intensity of the fluorescent guest implanted in the PCs. The modification of PCs on spontaneous emission is attracting current interests due to its considerable scientific and technological values. In this article, after highlight the international development on this field, on emphasis, we will introduce our recent results on the preparation of three-dimensional lanthanide oxide PCs through the self-assembly method and the modification of PCs on spontaneous emission of rare earth ions. Recently, we observed a number of interesting phenomena, such as the observation of Lamb shift, inhibited long-scale energy transfer ( ET) and improvement of luminescent quantum yield in lanthanide oxide inverse opal PCs.关键词
