A theoretical study of thermal management of FBAR considering thickness- and temperature-dependent thermal conductivity of AlN

open access: yesAIP Advances, 2022
Reliable and long-term operation of thin film bulk acoustic resonators (FBARs) under high power relies on the optimization of thermal resistance. In this work, thermal design strategies for high power FBARs are explored theoretically.

Lanthanide grafted phenanthroline-polymer for physiological temperature range sensing [PDF]

open access: yes, 2019
Accurate measurement of the temperature is crucial as it determines the dynamics of almost any system. Conventional contact thermometers are not well suited for small scale measurements. Temperature dependent luminescent materials, i.e.

Persistent luminescence in non-Eu2+-doped compounds : a review [PDF]

open access: yes, 2013
During the past few decades, the research on persistent luminescent materials has focused mainly on Eu2+-doped compounds. However, the yearly number of publications on non-Eu2+-based materials has also increased steadily.

Glucose sensor based on the LUQUEN-principle [PDF]

open access: yes, 1992
A new type of glucose sensor based on luminescence quenching (LUQUEN) is proposed. In this LUQUEN principle the concentration induced quenching is enlarged by radiationless (excited-state) energy transfer within the luminescent material.

Divalent europium-doped near-infrared-emitting phosphor for light-emitting diodes

open access: yesNature Communications, 2019
Here the authors report a near-infrared K3LuSi2O7:Eu2+ phosphor for non-visible light source application. The selective site occupation of Eu2+ in LuO6 and K2O6 polyhedrons is found to be responsible for the light emission and these insights could serve ...
