Bergman and M. Stockman proposed spaser in 2003 [1]. Recently, the lasing action of gold nanospheres in a dye-filled, glasslike shell immersed in a solution has been demonstrated [2,3] including three-dimensional lasing spaser made of photonic crystal containing self-assembled gold nanoparticles in dye-doped shell [3].

The spaser is analogous to the conventional laser. A spaser consists of a metal nanoparticle (NP) as the resonator surrounded by a nanoshell of the gain medium. In contrast, the spaser as a nanoscopic quantum generator of localized surface plasmons is a promising candidate for a wide range of applications because it allows beating the diffraction limit and focusing electromagnetic energy to spots much smaller than a wavelength.

Despite the first successful demonstration of spasing, no experimental demonstration of the spaser effect in a solution has ever been observed. However, overcoming these experimental difficulties enables the opportunity to demonstrate their potential applications, for example, in biomedicine [4].

Here, we experimentally demonstrate spasing in a solution of hybrid Au nanoparticles for visible and near IR region. To produce spasers we have fabricated hybrid nanoparticles with a 10-nanometre gold core or nanorods with a different aspect ratio surrounded by a 20-40-nanometre-thick silica shell, embedded with dye molecules (fluorescein or DCM). Here, progress in the study of spasers will be presented.
