In this work we study the luminescent properties of rare earths (RE) in porous
silicon monolayers (PS). Theoretical and experimental studies will be carried out
in order to understand the luminescent dynamics. We will develop a microscopic
model that models the individual behavior of each ER ion inside of SP. The
fundamental understanding of the optical behavior of PS:RE will be very useful
for the design of electronic systems that are capable of transmitting electrical
and optical signals simultaneously. Recently there has been a growing interest
in luminescent silicon, both in basic and applied research. Since microelectronic
devices are mainly made of silicon (S), the possibility of fusing microelectronics
and photonics in the same chip is a real possibility. In this way, even the
understanding of the luminescent behavior of silicon doped with rare earth is a
current theme. From the technological point of view, in the commutation signal
area, for example, it is of great interest not only to control, but also to predict
the luminescent behavior. Three of the most important luminescent properties
are: the luminescent intensity (quantum efficiency), the color coordinate and the
lifetime. The luminescent intensity refers to the amount of light emitted by the
material, the materials with high efficiency are able to convert the incident
energy into emission efficiently. The color refers to the wavelength of the signal
transmission. Finally, lifetime determines the time between pulse and pulse of
the optical signal. Optical technologies are increasingly important in areas that
have traditionally been the domain of electronic devices. The enormous
bandwidth that is available through optical communication allows the transfer
of information and the processing of data at rates that are several orders of
magnitude higher than the of electronic technology.
