A vanadate-based white light emitting luminescent material for temperature sensing

Abstract

White-light emitting CMV:Eu3+ sheets show a linear color variation depending on the ambient temperature.

The synergism between self-activated and impurity-related emissions of LiCa3ZnV3O12: lattice distortion, energy transfer and temperature sensing effect

“…The temperature-dependent PL characteristics of the samples were obtained by referring to the strategy in ref. 26 which was evaluated by heating the samples sealed in a metallic box and kept them at a particular temperature, and then rapidly transferring the sample at a specific temperature from the heater to the fluorescence spectrophotometer for measurement.…”

“…The temperature-dependent PL characteristics of the samples were obtained by referring to the strategy in ref. 26 which was evaluated by heating the samples sealed in a metallic box and kept them at a particular temperature, and then rapidly transferring the sample at a specic temperature from the heater to the uorescence spectrophotometer for measurement. Davolos' research shows that efficient ion substitution can be achieved when the ionic radii difference percentage (D r ) between dopant ions and replaced ions is within 30%.…”

Optical Thermometry by Monitoring Dual Emissions from YVO4 and Eu3+ in YVO4:Eu3+ Nanoparticles

“…Zhang et al reported Ca 5 Mg 4 V 6 O 24 :Eu 3+ powders for thermal sensing within 298−473 K range with thermal sensitivity of about 0.5% K −1 . 26 CaNb 2 O 6 :Eu 3+ and CaNb 2 O 6 :Eu 3+ ,Bi 3+ phosphors showed high thermal sensitivity of 1.8 and 3.8% K −1 , respectively. 27 Noteworthy, the reported thermometers have a quite complex host composition, which makes synthesis more difficult.…”

“…This approach was successfully realized by several scientific groups. Zhang et al reported Ca 5 Mg 4 V 6 O 24 :Eu 3+ powders for thermal sensing within 298–473 K range with thermal sensitivity of about 0.5% K –1 . CaNb 2 O 6 :Eu 3+ and CaNb 2 O 6 :Eu 3+ ,Bi 3+ phosphors showed high thermal sensitivity of 1.8 and 3.8% K –1 , respectively .…”

Tunable and white light photoluminescence from ZnO on porous Si with the addition of carbon quantum dots

“…White light emission has become a very important effect due to its application in displays, light emitting devices [1] and sensors [2][3][4]. More specifically, a host of different materials have been used to accomplish this effect, including yellow phosphor materials in combination with Si or III-V semiconducting diodes [1], organics [5], perovskites [6], quantum dots [7], metal-organic frameworks [8,9] and others.…”
