The metal nanoparticles have excellent local enhancements. The Bloch wave of the array structure couples with single particle localized surface- plasma resonances (LSPRs) by designing array structure, forming arrays support surface lattice resonances (SLRs)，which can obtained a larger quality factor and small pattern volume and increased the efficiency of the spontaneous emission. Diamond structure of nanoparticles can effectively gather charge, form a strong dipole resonance, which can achieve excellent characteristics including lower lasing threshold and higher spatial coherence.
