Licetus, 1640 (about the Bologna stone) 1.1 What Is Luminescence? The word luminescence, which comes from the Latin (lumen = light) was fi rst introduced as luminescenz by the physicist and science historian Eilhardt Wiede- mann in 1888, to describe “ all those phenomena of light which are not solely conditioned by the rise in temperature,” as opposed to incandescence. Lumines- cence is often considered as cold light whereas incandescence is hot light. Luminescence is more precisely defi ned as follows: spontaneous emission of radia- tion from an electronically excited species or from a vibrationally excited species not in thermal equilibrium with its environment. 1) The various types of lumines- cence are classifi ed according to the mode of excitation (see Table 1.1 ). Luminescent compounds can be of very different kinds: • Organic compounds : aromatic hydrocarbons (naphthalene, anthracene, phenan- threne, pyrene, perylene, porphyrins, phtalocyanins, etc.) and derivatives, dyes (fl uorescein, rhodamines, coumarins, oxazines), polyenes, diphenylpolyenes, some amino acids (tryptophan, tyrosine, phenylalanine), etc. + 3 + 3 + • Inorganic compounds : uranyl ion (UO 2 ), lanthanide ions (e.g., Eu , Tb ), doped glasses (e.g., with Nd, Mn, Ce, Sn, Cu, Ag), crystals (ZnS, CdS, ZnSe, CdSe, 3 + GaS, GaP, Al 2 O3 /Cr (ruby)), semiconductor nanocrystals (e.g., CdSe), metal clusters, carbon nanotubes and some fullerenes, etc. 1) Braslavsky , S. et al .

  • Energy Technology Innovation Leadership in the 21St Century
    ENERGY TECHNOLOGY INNOVATION LEADERSHIP IN THE 21ST CENTURY Hal Harvey, Jeffrey Rissman, and Sonia Aggarwal Technicians work on a 3-megawatt Alstom wind turbine and a 1.5-megawatt GE wind turbine at the National Wind Technology Center, the nation's premier wind energy technology research facility. www.energyinnovation.org EXECUTIVE SUMMARY A rich array of new energy options is a critical foundation for enduring prosperity, energy security, and the protection of the environment and public health. Smart policy can fill the pipeline with many energy technology options, bring the best of these options to market, and unleash the full power of the private sector in driving down their prices. Energy is profoundly a technology business, so it pays to understand which policies work best at stimulating energy technology innovation. This paper unpacks innovation—from risky science, with only distant potential for application, to the intense work of commercialization, wherein companies drive down costs, increase performance, and learn to deliver reliable products. To understand the set of needed policies, this paper divides innovation into three stages: research, engineering, and commercialization. It then examines which tools and practices work best for each stage. Research is by definition a risky business, and some projects will inevitably fail. However, well- managed research can deliver a far higher fraction of success than a piecemeal approach. For the research stage, four principals rise to the top: 1. Concentrate resources in innovation hubs; 2. Use peer review to select promising research domains that support explicit policy goals; 3. Ensure that policies intended to incentivize R&D are stable and predictable over the long time horizons (~10 years) necessary for R&D investment and technology development; 4.

  • Modeling Regulation of Economic Sustainability in Energy Systems with Diversified Resources
    Article Modeling Regulation of Economic Sustainability in Energy Systems with Diversified Resources Anatoly Alabugin and Sergei Aliukov * Higher School of Economics and Management, South Ural State University, Prospekt Lenina, 454080 Chelyabinsk, Russia; [email protected] * Correspondence: [email protected] Abstract: The imperfection of theoretical and methodological approaches to regulate the jump process transition when combining differentiated energy resources is a pressing issue. The goal of this paper is to develop a theory and a method to regulate the integration-balancing processes of combining diversified resources. The concept of combining integration and balancing models has been substantiated by methods of transforming multidimensional space and approximating generalized functions that represent jump-like processes. Theoretical and operational-regulatory models of economic sustainability have been developed, substantiating new concepts, patterns, prop- erties, dependencies and indicators of the dynamics of the processes of combination; the optimality conditions for the number of approximations of generalized functions, interpreting the effects of control functions of combining resources, are thus determined. New methods for solving problems have been developed: the organization of the energy technology complex of facilities for enhanced resource diversification and the Sustainable Development Center, improving the quality of managing dynamic processes in terms of combining and diversifying resources. Emphasis is placed on four
