Optimizing white light emission in Dy(iii) complexes: impact of energy transfer from mono and bidentate ligands on luminescence.

Complexes of dysprosium(iii) ions with 1,1,1,5,5,5-hexafluoro-2,4-pentanedione featuring various mono and bi-dentate neutral ligands have been prepared and thoroughly investigated. The synthesized complexes exhibit an octa-coordinated environment, achieved by stoichiometrically combining organic ligands and Dy(iii) ions. This octa-coordination environment of Dy(iii) ion was confirmed by FT-IR spectroscopy, thermogravimetry and elemental analysis. Near-white light (NWL) is emitted when complexes were exposed to UV radiation, indicating a significant flow of energy from the sensitizing moieties towards the Dy(iii) ion. This NWL emission might have resulted due to a balance between the intensities corresponding to emission peaks at 480 nm (blue) and 575 nm (yellow) in Dy1-Dy3. Emission spectra recorded at different excitation wavelength were utilized to study the tunability of CIE color coordinates. In addition to their high thermal stability, the complexes display bipolar paramagnetic shifts in their NMR spectra. The 4F9/2 → 6H13/2 transition, contributing ∼62% of the total emission, stands out as a promising candidate for laser amplification due to its dominance in the emission spectra. Additionally, NWL emission observed in a solid Dy(iii) complex opens intriguing possibilities for its application in next-generation white-light emitting devices.

The 2017 Academic College of Emergency Experts and Academy of Family Physicians of India position statement on preventing violence against health-care workers and vandalization of health-care facilities in India.

There have been multiple incidents where doctors have been assaulted by patient relatives and hospital facilities have been vandalized. This has led to mass agitations by Physicians across India. Violence and vandalism against health-care workers (HCWs) is one of the biggest public health and patient care challenge in India. The sheer intensity of emotional hijack and the stress levels in both practicing HCWs and patient relative's needs immediate and detail attention. The suffering of HCWs who are hurt, the damage to hospital facilities and the reactionary agitation which affects patients who need care are all together doing everything to damage the delivery of health care and relationship between a doctor and a patient. This is detrimental to India where illnesses and Injuries continue to be the biggest challenge to its growth curve. The expert group set by The Academic College of Emergency Experts and The Academy of Family Physicians of India makes an effort to study this Public Health and Patient Care Challenge and provide recommendations to solve it.
