A research team from ITMO University has used hybrid perovskites to create light-emitting nanoantennas with enhanced photoluminescence. The nanoantenna and light source are combined in a single nanoparticle. The new nanoantenna can generate, enhance and direct emission wavelengths. Hybrid perovskites were used because they are known to possess a high refractive index, and they support excitons at room temperature with high binding energies and quantum yield of luminescence. Nanoantennas obtained by the scientists change their emission wavelength depending on the material...Read full articleRelated content from Photonics MediaARTICLESQuantum Light Sources Realized Via Site-Selective Defect EngineeringWhen photons can be used to transmit information at the speed of light, quantum light sources, connected with quantum fiber optic cables and detectors, will be a requirement.

Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer. Lately demands from industry and research have...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookLaser Safety: Important Considerations: Laser safety is nothing to scoff at; lasers can be hazardous. Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookTransparent Ceramics: Enabling Large, Durable, Multifunctional Optics: Aluminum oxynitride and magnesium aluminate spinel are mechanically strong, hard and scratch resistant; they are also chemically durable.
