Synthesis and optical spectroscopy of Na₃Y(VO₄)₂:Eu³⁺ phosphors for thermometry and display applications

Abstract

A new NYVO:Eu3+ phosphor was prepared using the sol–gel method and its exhibits high-brightness and thermally stable emission that could be used for display and temperature sensing applications.

Recent progress in trivalent europium (Eu3+)-based inorganic phosphors for solid-state lighting: an overview

“…The optical thermometry of the phosphor was studied in the temperature range of 298–440 K, and found with maximum absolute and relative sensitivities of 3.4% K −1 and 0.0032 K −1 , respectively. 162…”

Ultrasensitive optical thermometry using Tb3+ doped NaSrGd(MoO4)3 based on single band ratiometric luminescence

“…3,6,7 Highly sensitive thermometers are in great demand in a range of sectors such as nanomedicine, integrated photonic devices, microfluidics, and nanoelectronics. [8][9][10] There are several varieties of spectroscopic characteristics that have been used to quantify temperature so far. The ones that are most often used are those that are based on an examination of the luminescence intensity ratio (FIR) of two emission bands.…”

Luminescent Properties and Charge Compensator Effects of SrMo0.5W0.5O4:Eu3+ for White Light LEDs

“…However, this approach typically generates a low color rendering index because of the lack of red light in the emission spectrum of the yellow phosphor. The solution is to add red phosphors that can be efficiently excited by blue light [ 6 , 7 ] or use the high-efficiency UV LED and the phosphors that can be excited by it [ 8 , 9 ]. As a result, it is critical to investigate red phosphors that can be successfully stimulated by blue light and UV light.…”
