The present invention is generally directed to methods of ozonating CNTs in fluorinated solvents (fluoro-solvents), wherein such methods provide a less dangerous alternative to existing ozonolysis methods. In some embodiments, such methods comprise the steps of: (a) dispersing carbon nanotubes in a fluoro-solvent to form a dispersion; and (b) reacting ozone with the carbon nanotubes in the dispersion to functionalize the sidewalls of the carbon nanotubes and yield functionalized carbon nanotubes with oxygen-containing functional moieties. In some such embodiments, the fluoro-solvent is a fluorocarbon solvent, such as a perfluorinated polyether.

A backlight includes an extended light source adapted to emit light. A reflective polarizer is disposed on the extended light source, such that for substantially normally incident light and for at least a first wavelength in a range from about 420 nanometer (nm) to about 650 nm, the reflective polarizer reflects at least 60% of the incident light having a first polarization state and transmits at least 60% of the incident light having an orthogonal second polarization state. A first prismatic film is disposed between the extended light source and the reflective polarizer. A retarder layer is disposed between the reflective polarizer and the first prismatic film, such that for substantially normally incident light at a wavelength of about 550 nm, the retarder layer has a retardance nW, where n is an integer ≥1 and W is a wavelength between about 160 nm and about 300 nm.
