Researchers developed a terbium(III) complex with salicylic acid hydrazide that produced predominantly green luminescence and was tested for anti-counterfeiting inks, latent fingerprint visualization, and several laboratory bioactivity measures. Under the study conditions, the material showed durable visible luminescence, resolved fingerprint details across varied surfaces, and produced preliminary antioxidant, antimicrobial, cytotoxic, and a-glucosidase-inhibitory results that require further validation.
