Broadband near‐infrared (NIR) phosphor‐converted light‐emitting diodes (pc‐LEDs) have
many prospective applications in areas related to food inspection, health management, plant …

The Cr 3+-activated phosphor properties are discussed in detail from an aspect of
spectroscopic point of view. The host materials considered here are a various kind of oxide …

Near-infrared (NIR) emitting LED devices have broad applications. Using a visible light LED
chip to excite Cr3+-activated phosphors to obtain NIR light has attracted extensive attention …

Transparent Cr 2 O 3-doped alumina ceramics were prepared by slip casting, followed by
pre-sintering in ambient atmosphere and hot isostatic pressing. The effect of dopant …

Abstract MgAl 2 O 4: Cr 3+(0.01–0.11 mol) doped nanocrystalline powders were prepared
by a combustion method at low temperature. The Scherer's method was used to estimate …

The energy level transitions in phosphor materials critically determine their emission
characteristics, and accurately predicting the energy level distribution of ions in these …

This paper reports the synthesis and characterization of Cr3+-doped alumina by the sol-gel
non-hydrolytic methodology. The resulting sample was treated at different temperatures. X …

The quest for optimized rare earth glass host is ever-increasing. Multi-component telluro-
borate glass matrices are excellent rare earth host due to their unique spectroscopic traits …

Abstract Ba 2 Mg (BO 3) 2–Ba 2 Ca (BO 3) 2 solid-solution doped with Eu 3+ has been
synthesized by the conventional solid-state reaction. The symmetry is lower for Ba 2 Ca (BO …
