• those thinner nanorods with diameters smaller than 1 μm. Light emission from NDs is coupled to the microrod cavity and WGM resonances behind the PL spectrum leads to enhancement of luminescence at positions aside the emission band peak, making the PL peak shift and the band shoulders prominent. Fabry

• , but also other functional crystals grown by the epitaxy process. Micro-PL measurements on a single ZnO nanorod containing luminescent NDs demonstrates that the light emission from NDs can be coupled to the nanorod cavity, resulting in shift of the PL emission peak and change of the PL spectrum shape

• spectra. Figure 6b shows the room temperature PL spectra of aged samples S2’ and S3’ showing an enhanced visible light emission and a suppressed near band edge (NBE) emission. The weak NBE emission from the ZnO nanocrystals strongly indicates the presence of a passivating Zn(OH)2 surface layer [16], as

Applied with a pulsed voltage (pulse duration of about 15 µs, repetition rate of about 1 kHz) this lamp produces a bright light radiation (see Figure 5). The light emission of this lamp originates

An inhomogeneity of the light emission over the anode surface (see Figure 6) is owing to the usage of experimental laboratory-level technologies

• recorded with an optical setup according to Hanbury Brown and Twiss. As seen in Figure 9a, a clear antibunching effect (g(2)(τ) < 1) can be observed at zero time delay (τ = 0) from an optical cavity with 1.6 µm diameter. This is strong evidence for nonclassical light emission. The depth of the antibunching
