We develop a simple yet rigorous theory of the enhancement of optical absorption and emission by molecules placed in the vicinity of metal nanoparticles. Both enhancement effects exhibit strong dependence on the nanoparticle size. Using the example of Ag nanospheres embedded in GaN, we show that strong enhancement can be obtained only for those quantum dots, atoms, or molecules that are originally...
At room temperature, CO 2 is transparent in the ultraviolet (UV) at wavelengths longer than 205nm; however, at temperatures above 1000K the CO 2 absorption cross-section becomes significant in the region between 200 and 320nm. Because CO 2 is a major product of hydrocarbon combustion and because both the magnitude of the absorption cross-section and the shape of the UV absorption...
