摘要: The attentuated-total-reflection technique was used to excite surface plasmons in thin silver films on various substrates. efficiency of conversion the into visible light at silver-air interface measured as a function film thickness and roughness. Approximate efficiencies for 50-nm-thick were 5% glass substrates, 9% Ca${\mathrm{F}}_{2}$-roughened up 80% holographic gratings.
