Understanding the surface processes (deposition and surface diffusion) that occur at or close to the surface of growing nanoparticles is important for fabricating reproducibly stellated or branched gold nanoparticles with precise control over arm len

We demonstrate self-assembly of microbottle resonators (MBRs) that support high-quality-factor (high- $Q$ ) whispering gallery modes (WGMs). Polymethyl methacrylate (PMMA), a transparent organic polymer, has been used for the self-assembly. Active MB

Phosphor materials with broad spectral range and an average emission lifetime (20 μs) have been achieved from carbon dots (CDs)-NaCl crystals. A one-pot synthesis pathway has been developed for CDs-NaCl crystals formation at room temperature. Precur

A photonic nanojet (PNJ) from a microcavity is a narrow and intense beam of light used to enhance the emerging electric field. Metal nanoparticles (NPs), on the other hand, confine a strong field in their vicinity due to the resonance of the free ele

Whispering gallery modes (WGMs) occur due to total internal reflection in symmetric dielectric structures. These modes have high quality (Q) factor and low mode volume (Veff). Photoluminescence (PL) of an emitter when coupled with WGMs leads to the m

Fluorescent nanodiamonds (NDs) are hard, nontoxic, have high melting point and possess physical and chemical stability. In this paper, the NDs with nitrogen vacancy (NV) centres have been studied with steady-state and time-resolved photoluminescence
