Ultralow-threshold upconversion infrared vision via a microsphere-mediated directional photofield
Constructing micro-/nanostructure-modulated photofields in upconversion devices to absorb low-energy photons and emit high-energy light is revolutionary for bioimaging, lasers, and photovoltaics, with proven capability to boost upconversion luminescence (UCL) by orders of magnitude. However, photoenergy dissipation and inadequate absorption result in excitation thresholds exceeding 1 mW/cm2, which exceeds retinal safety limits and hinders wearab…
Humans Can Get Super Vision From These Contact Lenses
Here are some contact lenses you definitely won't want to wear to bed. A team of scientists from China and the University of Massachusetts has created contacts that allow people to see in total darkness and even with their eyes shut, according to a study published in the journal Cell....
Contact lenses developed by Chinese researchers help people see wavelengths of color that are not visible to the human eye. Chinese researchers have developed new contact lenses that allow people to see infrared light frequencies and could restore color vision to color-blind people. The researchers say the contact lenses could allow people to achieve supervision even with their eyes closed. The contact lenses use nanoparticles that absorb low-fr…
Science-fiction – or the future of seeing? Chinese scientists:inside have developed a contact lens with which people can perceive light in the infrared area without further aids. read more on t3n.de
