Electricity consumption for lighting is over 15% world's total electricity, thereby contributing to
the 5% of worldwide greenhouse gas emissions. By 2030, a 50% rise in lighting demand of …

The double perovskite phosphor materials are physically, chemically and thermally stable in
nature. The generalized formula of double perovskite is AA'BB'O 6 type. The transition metal …

High light-quality and low color temperature are two crucial factors for a comfortable healthy
illumination. Phosphor-converted white light-emitting diodes (LEDs) could be readily …

High color rendering index (CRI), low correlation color temperature (CCT) and excellent
thermal stability are crucial indicators to evaluate the practical applications of the white light …

Fingerprints are widely studied due to their unique shape and lifelong properties. The latent
fingerprint (LFP) visualization is critical in identifying crime scenes and personal information …

Red phosphor plays a key role in improving the lighting and display quality of phosphor-
converted white light-emitting diodes (pc-WLEDs). Meanwhile, developing new luminescent …

Exploring high efficiency narrow-band phosphors is an important enabler for the wide color
gamut, high color rendition and visual luminous efficacy of the illumination and display …

Narrow band red-emitting phosphors are significant constituents but still a bottleneck for next-
generation smart displays and high-performance lighting (solid-state lighting based white …

A strategy of optical temperature sensing was developed by using various thermal
quenching of Mn4+ and Eu3+ for double perovskite tellurite phosphor in optical …

Abstract Pristine ZrO 2 and Eu 3+ activated ZrO 2 nanophosphors were synthesized by urea
assisted solution combustion method. The synthesized nanophosphors were characterized …
