Transition metal (TM) ion activated phosphors are increasingly being used as probes for
luminescence thermometry. Their luminescence is characterized by strong absorption and …

This article puts emphasis on the role of phosphors in the advancement of Light-emitting
diodes (LEDs). The increasing use of phosphors in LEDs, consequently, led to the …

Endowing a single material with various types of luminescence, that is, exhibiting a
simultaneous optical response to different stimuli, is vital in various fields. A …

The development of current technology imposes more and more requirements for
measurement techniques, where one of the most important is temperature measurement. In …

The development of extra‐broadband emitting phosphors is challenging but meaningful
work. So far, however, phosphors that can be effectively excited by GaN‐based blue light …

Finding narrow-band light emitters for the visible spectral region remains an immense
challenge. Such phosphors are in great demand for solid-state lighting and display …

Solid‐state lighting is advancing toward higher power, higher brightness, and smaller size to
cope with the market competitiveness, and laser‐driven solid‐state lighting technology is …

Over recent years, Mn (II)‐organic materials showing circularly polarized luminescence
(CPL) have attracted great interest because of their eco‐friendliness, cheapness, and room …

Over the last decade, narrow-band emitters have been recognized as key enablers for light
emitting diodes (LEDs) backlights in liquid-crystal displays (LCDs) by competing with other …

In this work, we report on the promising photoluminescent behavior of the cubic double
perovskite Cs2NaBiCl6 doped with Mn2+ ions. Localized excitations centered on Bi3+ ions …
