Quantum dots (QDs) is a new material with special photoelectric properties, whose optical nonlinearity is potentially and widely applied in laser protection and photoelectric devices. This thesis concludes the research progresses on quantum dots’s composition and superficial decoration means in organic polymer system and its linear and nonlinear effects and introduces the researches on the application of quantum dots.
Quantum dots (QDs) is some material which particle size is between 1 to 10 nanometers. Because of the unique
nonlinear optical properties, QDs has been widely applied in optical, electrical, magnetic, biological fields etc. Though
the size of the nanoscale is bringing the QDs a series of characteristic advantages, it has also brought some problems for
further application, such as QDs are easily degenerative according to their small size. However, The preparation of
quantum dots with special polymer composite film can avoid this phenomenon, This means that the composite is usually
with inert matrix can be realized for further application.
