Polaritons emerge in semiconductors placed within optical microcavities when non-dissipative, coherent energy exchange between excitons and the microcavity optical modes (i.e., standing electromagnetic waves) dominates over the system\u0027s energy losses. This regime is also known as strong light-matter coupling.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThis Ph.D. thesis overcomes challenges of exciton-polaritons in organics and two-dimensional metal halide semiconductors at two distinct fronts: the fabrication of photonic structures with strong light-matter coupling and the characterization of exciton-polariton photophysics. We enable polaritons in a wider variety of materials by developing non-destructive fully solution-processed microcavities, which offer the required electromagnetic field enhancements for strong light-matter coupling and are highly compatible with temperature-sensitive semiconductors. These microcavity structures are produced from solution at ambient conditions using common processing methods (i.e., dip coating) and comprise a high-refractive-index titanium oxide hydrate\/poly(vinyl alcohol) hybrid material and low-refractive-index commodity polymers. On the other front, we identify nonlinear processes that build up and hinder the population of exciton-polaritons in these material classes. We resolve nonlinear processes that are faster than the polariton lifetime (\u0026lt;\u0026lt;1 ps) and comparable to the exciton lifetime (\u0026gt;\u0026gt;1 ps) by utilizing excitation correlation photoluminescence spectroscopy and two-dimensional coherent spectroscopy, respectively. This is a key milestone towards developing guidelines for populating large ensembles of exciton-polaritons, as required for polariton-based technologies. The work presented in this thesis moves us forward toward practical applications of room-temperature exciton-polaritons.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003EDr. Natalie Stingelin \u2013 Schools of MSE \u0026amp; ChBE, Georgia Institute of Technology (advisor)\u003C\/li\u003E\u003Cli\u003EDr. Carlos Silva-Acu\u00f1a \u2013 School of Physics, Universit\u00e9 de Montr\u00e9al (advisor)\u003C\/li\u003E\u003Cli\u003EDr. Juan-Pablo Correa-Baena \u2013\u0026nbsp;School\u0026nbsp;of\u0026nbsp;MSE, Georgia Institute of Technology\u003C\/li\u003E\u003Cli\u003EDr. Antonio Facchetti \u2013 School of MSE, Georgia Institute of Technology\u003C\/li\u003E\u003Cli\u003EDr. Joshua Kretchmer \u2013 School of Chemistry, Georgia Institute of Technology\u003C\/li\u003E\u003Cli\u003EDr. Phillip N.
