    Abstract: This book is a comprehensive collection of information about the features, functions, and services of aquatic macrophytes. As primary producers, aquatic macrophytes form the basis of food webs, play a major role in highly productive aquatic ecosystems, and have a significant impact on ecosystem functions and services. Macrophytes are also known to strongly influence the micro-climate and biogeochemical processes occurring in the littoral zones of marine ecosystems and the sediment dynamics of freshwater systems. They also serve as highly effective carbon sinks and play an important role in carbon sequestration. This book deals with various aspects of aquatic macrophytes, including nutrient recycling, biogeochemical processes, biomass production, wetland ecosystems, water resource management, carbon sequestration, environmental clean-up, and bioenergy production. Additionally, it presents the current status of aquatic macrophytes and discusses the impact of climate change on these plants. The book also highlights the major challenges associated with harnessing the benefits provided by aquatic macrophytes as ecosystem services. The book holds value and relevance for academicians and scientists working in the related domain. Additionally, it will serve as a valuable resource for students and researchers working in the field of ecology, biogeochemistry, wetland conservation, phytoremediation, elements biomonitoring, wastewater management, bioenergy production, etc.

    Notes: We obtain the temperature dependence of the homogeneous linewidth of excitons in GaAs quantum wells (QWs) and bulk GaAs using photoluminescence measurements. The results indicate that exciton scattering rates with optical phonons are larger in bulk GaAs than in QWs. © 2000 American Institute of Physics.

    Notes: We study the picosecond dynamics of free carriers and excitons in high-quality GaAs quantum wells at 8 K using frequency upconversion (UC) and nonlinear picosecond excitation-correlation (PEC) luminescence spectroscopy under nonresonant excitation conditions with carrier densities of a few 1010 cm−2. We analyze the measurements using a theoretical model of the coupled free electron–hole pair and exciton dynamics, incorporating important density-dependent nonlinear effects, caused by exciton collisions and fermion exclusion. The time-resolved UC photoluminescence (PL) spectra are used to deduce time constants related to free electron–hole (e–h)-pair transformation into excitons and exciton transfer from large K to small K (k is the exciton wave vector). It is shown that unambiguous determination of exciton radiative and nonradiative decay times are possible when both UC and PEC PL spectra are considered simultaneously. We carry out a detailed line-shape analysis of the picosecond UC and PEC PL spectra. We find that while collision broadening is mainly responsible for the observed nonlinear excitonic PEC signal, the PEC PL spectra can be fully explained only when additional nonlinear effects, such as density-dependent radiative lifetime and fermion exclusion, are included in the analysis. From a comparison of the time evolution of both the PEC and UC PL spectra with theory, the time constants introduced in the model to describe free carrier density decay, transfer of excitons with K≠0 to K≈0 states, and their radiative and nonradiative decay are estimated to be about 50, 15, 60, and 1800 ps respectively. © 1996 American Institute of Physics.
