“…However, the most interesting is the antiresonant behaviour under 2.54 eV excitation, which reveals a quick decrease of the (1) intensity of almost 2 orders of magnitude in the temperature range from 80 to 140 K. It results in the complete vanishing of the (1) mode for range from 150 K to 180 K. At higher temperatures, slow linear growth of the (1) intensity is visible. This shape of the (1) intensity reflects the reported enhancement profile for this mode as a function of excitation energy in InSe in the vicinity of the B transition 30 , 47 . Consequently, we can speculate that the B transition energy varies from about 2.54 to 2.41 eV with temperature changes from about 50 to 270 K. The origin of the antiresonance can be described similarly to GaSe in terms of quantum interference.…”

“…Moreover, we believe that the assumption that the temperature evolution of the B transition is similar to the optical band gap in InSe [44][45][46] may lead to misestimation. (1) intensity reflects the reported enhancement profile for this mode as a function of excitation energy in InSe in the vicinity of the B transition 30,47 . Consequently, we can speculate that the B transition energy varies from about 2.54 to 2.41 eV with temperature changes from about 50 to 270 K. The origin of the antiresonance can be described similarly to GaSe in terms of quantum interference.…”

The temperature effect on the Raman scattering efficiency is investigated in $$\varepsilon$$ ε -GaSe and $$\gamma$$ γ -InSe crystals. We found that varying the temperature over a broad range from 5 to 350 K permits to achieve both the resonant conditions and the antiresonance behaviour in Raman scattering of the studied materials. The resonant conditions of Raman scattering are observed at about 270 K under the 1.96 eV excitation for GaSe due to the energy proximity of the optical band gap. In the case of InSe, the resonant Raman spectra are apparent at about 50 and 270 K under correspondingly the 2.41 eV and 2.54 eV excitations as a result of the energy proximity of the so-called B transition. Interestingly, the observed resonances for both materials are followed by an antiresonance behaviour noticeable at higher temperatures than the detected resonances. The significant variations of phonon-modes intensities can be explained in terms of electron-phonon coupling and quantum interference of contributions from different points of the Brillouin zone.

Background Little is known about the quality of life (QoL) of caregivers of patients with chronic kidney disease (CKD) along the disease continuum. We investigated factors associated with low QoL among caregivers of patients with CKD including those on dialysis. We also examined the relationship between kidney disease severity and the QoL of caregivers. Methods We recruited caregivers of patients with CKD (stage 3 to 5) attending renal outpatient clinics as well as dialysis units of a tertiary hospital and patients from January 2018 to November 2023. Quality of life was assessed using a valid and reliable tool, the Adult Carer Quality of Life Questionnaire. Logistic regression analyses were performed to determine factors associated with low QoL among caregivers. Results A total of 278 dyads of caregivers and patients were studied with a mean age of 56.6 ± 15.2 and 63.7 ± 15.3 years respectively. The proportion of caregivers reporting low to mid-range QoL scores ranged from 37 to 73.3% across the eight domains, with 48% having low to mid-range overall QoL scores. The severity of CKD had no impact on overall QoL of caregivers in the personal growth and carer satisfaction domains where caregivers of patients on dialysis reported worse scores compared to caregivers of predialysis patients. Female gender of caregivers and patients, longer caregiving time, diagnosis of diabetes and lower socioeconomic status of patients were all associated with lower scores in one or more domains. Conclusion This study identified several factors associated with low QoL among caregivers of patients with CKD. An understanding of these factors provides insight into the development of targeted interventions to improve the QoL of caregivers.
