Pressure-Induced Remarkable Spectral Red-Shift in Mn2+ -Activated NaY9 (SiO4 )6 O2 Red-Emitting Phosphors for High-Sensitive Optical Manometry. [PDF]

open access: yesAdv Sci (Weinh), 2023
To settle the low sensitivity of luminescent manometers, the Mn2+‐activated NaY9(SiO4)6O2 red‐emitting phosphors with splendid pressure sensing performances are developed.

A general strategy to red-shift green fluorescent protein-based biosensors. [PDF]

open access: yesNat Chem Biol, 2020
Compared with green fluorescent protein-based biosensors, red fluorescent protein (RFP)-based biosensors are inherently advantageous because of reduced phototoxicity, decreased autofluorescence and enhanced tissue penetration. However, existing RFP-based

Massive red shift of Ce3+ in Y3Al5O12 incorporating super-high content of Ce. [PDF]

open access: yesRSC Adv, 2020
In light emitting diodes, Y3Al5O12:Ce (YAG:Ce) is used as a yellow phosphor in combination with blue LEDs but lacks a red component in emission.

Crystal Chemistry, Band-Gap Red Shift, and Electrocatalytic Activity of Iron-Doped Gallium Oxide Ceramics. [PDF]

open access: yesACS Omega, 2020
This work for the first time unfurls the fundamental mechanisms and sets the stage for an approach to derive electrocatalytic activity, which is otherwise not possible, in a traditionally known wide band-gap oxide material. Specifically, we report on the

Investigation into the Photoluminescence Red Shift in Cesium Lead Bromide Nanocrystal Superlattices. [PDF]

open access: yesJ Phys Chem Lett, 2019
The formation of cesium lead bromide (CsPbBr3) nanocrystal superlattices (NC SLs) is accompanied by a red shift in the NC photoluminescence (PL). The values of the PL red shift reported in the literature range from none to ∼100 meV without unifying ...

Discovery of carotenoid red-shift in endolithic cyanobacteria from the Atacama Desert. [PDF]

open access: yesSci Rep, 2017
The biochemical responses of rock-inhabiting cyanobacteria towards native environmental stresses were observed in vivo in one of the Earth’s most challenging extreme climatic environments.

Long tailed trions in monolayer MoS2: Temperature dependent asymmetry and resulting red-shift of trion photoluminescence spectra. [PDF]

open access: yesSci Rep, 2017
Monolayer molybdenum disulfide (MoS2) has emerged as a model system for studying many-body physics because the low dimensionality reduces screening leading to tightly bound states stable at room temperature. Further, the many-body states possess a pseudo-

A Strap-Down Inertial Navigation/Spectrum Red-Shift/Star Sensor (SINS/SRS/SS) Autonomous Integrated System for Spacecraft Navigation. [PDF]

open access: yesSensors (Basel), 2018
This paper presents a new Strap-down Inertial Navigation System/Spectrum Red-Shift/Star Sensor (SINS/SRS/SS) system integration methodology to improve the autonomy and reliability of spacecraft navigation using the spectrum red-shift information from ...

Testosterone Administration Induces a Red Shift in Democrats [PDF]

open access: yesBrain and Behavior
Objective An experiment was run to test if a testosterone administration would influence the political preferences of 136 healthy males. Method Synthetic testosterone or placebo was administered to participants who identified the strength of their ...

Red‐shifts and red herrings in geographical ecology [PDF]

open access: bronzeEcography, 2000
I draw attention to the need for ecologists to take spatial structure into account more seriously in hypothesis testing. If spatial autocorrelation is ignored, as it usually is, then analyses of ecological patterns in terms of environmental factors can produce very misleading results.
