Growth Kinetics And Electronic Properties Of Semiconducting Nanocrystals In The Quantum Confined Regime
(2009-03-04)
Properties of nanocrystals are extremely sensitive to their sizes when their sizes are smaller or of the order of the excitonic diameter due to the quantum confinement effect. The interest in this field has been concentrated ...
Excitation Energy Transfer In Donor-Acceptor Systems Involving Metal Nanoparticles, And In Conjugated Polymers
(2013-02-19)
This thesis consists of two parts and nine chapters. The first part (Part I) presents theoretical studies on non-radiative mode of excitation energy transfer (EET) in donor-acceptor (D-A) systems involving metal nanoparticles. ...
Doping And photophysical Properties Of II-VI Semiconductor Nanocrystals
(2010-06-03)
Semiconductor nanocrystals with sizes comparable to the corresponding bulk excitonic diameter exhibit unique size-dependent electronic and optical properties resulting from quantum confinement effect. Such nanocrystals not ...
Synthesis, Structure And Redox Catalytic Properties Of Pt And Pd Ion Substituted Ce1-xMxO2(M= Ti, Zr & Hf) Oxygen Storage Capacity Nano-materials
(2010-09-28)
Three-way catalysis (TWC) involves simultaneous removal of the three pollutants (i.e., CO, NOx, and HCs) which led to the branch of auto-exhaust catalysis. CeO2 has become the main component of TWC catalyst because of its ...
Internal Structure and Self-Assembly of Low Dimensional Materials
(2018-05-01)
The properties of bulk 3D materials of metals or semiconductors are manifested with various length scales(e.g., Bohr excitonic radius, magnetic correlation length, mean free path etc.) and are important in controlling their ...
Investigation On Ag And ZnO Based Nanohybrids As Bactericides For The Purification Of Water And Elucidation Of Possible Mechanisms For Their Bio-activity
(2015-12-02)
Chapter I: This chapter briefly gives an introduction about microorganisms, their varieties, growth, reproduction etc. In particular, about bacterial function. A sincere attempt is made to review this briefly, including ...
