In this age of technology, people are inevitably surrounded by electronic devices and light-
emitting devices, but the radiation generated by these devices is very harmful to humans …

The research and development of non-toxic, broad-spectrum and environmentally friendly
ultraviolet absorbers remains no significant progress in recent years. We found that the …

Our skin and materials are constantly exposed to detrimental ultraviolet light (UV) rays from
the sun. It is essential to protect our health and the life of materials by intercepting this …

Liquid Carbon Dots (CDs) were successfully synthesized by hydrothermal method using
urea and citric acid as raw materials. TEM images confirmed that the CDs have a spherical …

In recent years, as the global climate continues to deteriorate, the harm of ultraviolet (UV)
radiation to the human body is increasing, but the development of commercial UV-blocking …

Using biomass materials to prepare carbon dots (CDs) has received significant interest. As a
cheap and environmentally friendly material, waste leather scrap can be used for the …

Our eyes and skin are routinely exposed to hazardous ultraviolet light (UV) from sunlight as
well as to high-energy blue light (HEBL) from modern IT devices. Therefore, it is essential to …

In the process of commercialization, it is critical to develop appropriate routes to decrease
the pollution and the cost for preparing and purifying carbon nanomaterials in a large scale …

Carbon dots (CDs), as a kind of carbon nanomaterials, have attracted widespread attention
due to their unique structure and excellent optical properties, and they are low-cost …

Herein, we present a facile approach to produce long-wavelength emitting carbon dots
(CDs). A shift of the fluorescence emission wavelength of CDs from 630 nm to 520 nm can …
