This proposal involves the investigation of linear and nonlinear phenomena in micro- nano-optical cavities and waveguides; the understanding of the limiting effects of each material, the understanding of the interaction between matter and light, including spontaneous and stimulated emission and the coupling between light, matter, and mechanical degrees of freedom in these structures. Also…
In the last two decades, colloidal semiconductor nanostructures are among the most investigated materials due to their unique set of properties, including the control of their optical and electronic properties by engineering their shape, size and composition, that turns them promising candidates for application in a vast range of areas, such as, energy harvesting, lighting, and Medicine. …
This project is aimed to investigate Random Lasers, which are based on laser emission in disordered media, in the absence of optical cavity. New methods for operation of random lasers and basic emission mechanisms and optical amplification will be investigated. In particular, we will study Random Lasers that operates based on frequency upconversion and multi-photon absorption in semicond…
Colloidal semiconductor nanomaterials form a class of materials that offers the possibility for studying the physics of highly confined electrons and open opportunities for applications on several areas. However, a number of important electronic phenomena occur on a ultra-short timescale, from hundreds of femtosecond to some picoseconds and their spectral behavior are hidden underneath th…
The Ultrafast Spectroscopy Laboratory at the University of Campinas has been working on understanding electronic dynamics in a series of novel optical materials including semiconductor nanomaterials, and graphene.

The candidate will use multi-dimensional coherent spectroscopy and single-dot spectroscopy to investigate the fine structure in NIR emitting semiconductor nanomaterials, including CuInS2 (CIS) and PbS nanoparticles.
Semiconductor nanoparticles are an important class of functional materials with potential for many applications, such as photovoltaic, light emission diodes, solar concentrators, biomarkers, lasing media, and single photon sources. Many studies reported in the literature discuss their linear and nonlinear optical properties depending on their composition, shape, size, crystalline structur…
In this project the student will explore the non-linear optical properties and the multi-exciton interactions in all-inorganic perovskite nanoplatelets. The goal is to understand how the nanoplatelets aspect ratio affect both properties, which could result in optimum material for application in LEDs or lasers.

There is no electronic method able to measure laser pulses shorter than 10-12 s (1 ps), consequently, for those mesaurements, it is necessary to apply methods based on nonlinear optical phenomena, such as second harmonic generation and two-photon absorption. In this proposal, we will develop a system for ultrashort pulses measurements (~100 fs) based on the photoluminescence excited by tw…
This project aims at training the student in subjects related to optical spectroscopy of nanomaterials. Therefore, it is proposed a work in which the student will have experience with the assembly of optical systems, programming, and photo-physics studies of nanometric semiconductors. This will be achieved through the mounting of a photoluminescence spectroscopy system excited by absorpt…
The candidate will help to setup a single-particle spectroscopy system that operates in the NIR region. With this system, peculiarities of the emission, which are hidden underneath the broad photoluminescence spectra, will be investigated in nanomaterials, including CIS and PbS nanoparticles. This system will also be used to study visible emitting nanomaterials, mainly perovskites and InP…

Greenhouse and indoor farming are promising alternatives to traditional growing systems due to the possibility of improved control over the raw material for plant cultivation resources, even using smaller cultivable areas. Beyond that, crop production in both the aforesaid systems can be increased by tailoring the spectrum of the light that reaches the plant leaves to ideal conditions, fa…
