TL;DR: In this article, the current-reversal spectra of high pressure Na-Hg-Xe and Na-CdXe lamps were analyzed and the existence of additional structure in the case of NaCd and NaHg blue diffuse bands was revealed.
Abstract: We present the current-reversal spectra of the high pressure Na-Hg-Xe and Na-Cd-Xe lamps, from which the specific NaHg and NaCd structured continua have been observed. Detailed analysis revealed the existence of additional structure in the case of NaCd and NaHg blue diffuse bands. In the NaHg case the neighbourhood of the 330 nm sodium line revealed two satellite bands of NaHg origin, but almost no structure around the 330 nm sodium atomic line was found in the case of Na-Cd-Xe discharge lamp.

TL;DR: Sodium high pressure lamp technology has been applied to develop a new high pressure zinc lamp, which is for the first time used for curing composite materials, and results of polymerisation measurements show that future improvements over the usual halogen light sources are possible.
Abstract: Polymerisation characteristics of conventional units for curing composite resins are insufficient considering handling feasibilities particularly in the premolar and molar region. There is also hazardous ocular effect of near ultra-violet part of visible spectra. Sodium high pressure lamp technology has been applied to develop a new high pressure zinc lamp, which is for the first time used for curing composite materials. The results of polymerisation measurements show that future improvements over the usual halogen light sources are possible. Zinc lamp was also compared with the high pressure sodium lamp filled with mercury or cadmium.
