摘要：
Single photon emission from an epitaxially grown quantum dot at room temperature is presented. CdSe/ZnSSe quantum dots are embedded into MgS barriers, providing dominant radiative recombination up to 300 K. Under continuous wave optical excitation, the autocorrelation function g(2)(t) exhibits a sharp dip at (t = 0) with g((2))(0) = 0.16 +/- 0.15 at T = 300 K, revealing excellent suppression of multiphoton emission even at room temperature.
