“…In other words, the Au NPs act as antennas to receive the incident light and transfer the energy of LSPR into CdSe NBs via near‐field plasmonic wave . Therefore, the absorption of the APH@CdSe NBs was quickly increased in the range of 538–580 nm, the so‐called plasmonic resonance absorption of Au nanoparticles, except near‐band‐edge absorption at ≈710 nm. It is found that the absorption peak caused redshifts to occur with increasing sputter time.…”

Noble metal nanoparticles have been demonstrated by a huge application prospect for photodetector (PD) due to their unique and tunable optical properties. Herein, a simple strategy is presented by a combination of gold nanoparticles (Au NPs) and broadband photoresponse cadmium selenide nanobelts (CdSe NBs) to get ultrasensitive, broadband photoresponse (300–720 nm) and tunable photoresponse PD. Concretely, the Au NPs are fabricated on CdSe NBs via ion sputtering and annealing, and the morphology of Au NPs is systematically adjusted by simply tuning the sputter time from 60 to 140 s. Compared with the pure CdSe NB PD, the Au NPs hybrid CdSe NB PD exhibits a high responsivity, especially in the range of 525–575 nm with low light intensity (enhancement of ≈2894% at 550 nm with 79.6 μW cm−2). The response time of the hybrid PD is decreased substantially from 0.8 to 0.2 ms. More importantly, the hybrid PD possesses a tunable absorption in the range of 538–580 nm, which is benefited from tunable plasmon resonance of Au NPs. These results are confirmed by the theoretical simulation. It is believed that this strategy offers new opportunities to design ultrasensitive, broadband spectra, and tunable wavelength PD.

A vast range of insulating, semiconducting, and metallic nanomaterials have been studied over the past several decades with the aim of understanding how continuous-wave or pulsed laser radiation can influence their chemical functionality and local environment. Many fascinating observations have been made during laser irradiation including, but not limited to, the superheating of solvents, mass-transport-mediated morphology evolution, photodynamic therapy, morphology dependent resonances, and a range of phase transformations. In addition to laser heating, recent experiments have demonstrated the laser cooling of nanoscale materials through the emission of upconverted, anti-Stokes photons by trivalent rare-earth ions. This Focus Review outlines the analytical modeling of photothermal heat transport with an emphasis on the experimental validation of anti-Stokes laser cooling. This general methodology can be applied to a wide range of photothermal applications, including nanomedicine, photocatalysis, and the synthesis of new materials. The review concludes with an overview of recent advances and future directions for anti-Stokes cooling.

Silicon nanoparticles possess unique size-dependent optical properties due to their strong electric and magnetic resonances in the visible range. However, their widespread application has been limited, in comparison to other (e.g. metallic) nanoparticles, because their preparation on monodisperse colloids remains challenging. Exploiting the unique properties of Si nanoparticles in nano-and micro-devices calls for methods able to sort and organize them from a colloidal suspension onto specific positions of solid substrates with nanometric precision.Here, we demonstrate that surfactant-free Silicon nanoparticles of a predefined and narrow ( < 10 nm) size range can be selectively immobilized on a substrate by optical printing from a polydisperse colloidal suspension. The size selectivity is based on differential optical forces that can be applied on nanoparticles of different sizes by tuning the light wavelength to the size-dependent magnetic dipolar resonance of the nanoparticles. TEXT The theoretical and experimental advances in plasmonics have led to remarkable control in squeezing, enhancing and manipulating optical electric fields on the nanoscale. 1-3 More recently, a new research front has emerged focusing efforts on understanding and exploiting optical magnetic resonances of high refractive index (HRI) nanoparticles (NPs). Initially conceived to control the magnetic component of light through optically induced Mie resonances, HRI NPs have found further applications due to their reduced dissipative losses in comparison to metals and to the possibility of confining both electric and magnetic fields. 4-9
