| Outline of Final Research Achievements |
Since rare-earths are luminous at various wavelengths intrinsic to the elements, assembling rare-earth doped materials into devices realizes selectable-color emitters suitable for diverse industrial purposes. The rare-earth dopants which couple with surroundings electronically and/or energetically may have positive and negative effects in the emission intensity. We identified the atomic scale interactions by using electromagnetic technique in microwave region. Various high frequency properties such as microwave propagation, charge response, emission response, propagation of harmonics, and electronic noise, are successfully applied to the evaluations of local charge and energy transfers/dissipations. The microwave properties explained emission properties of the doped rare-earth consistently. From the results, guidelines for intensification of frontier devices such as GaN:Eu red LED are drawn up.
