Abstract
An improved phosphor admixture is provided for an electroluminescent cell or lamp which reduces the electric arc susceptibility during normal operation. Said phosphor admixture includes an electrically non-conductive, same color light-transmitting particulate solid as a means of reducing the current density of said electroluminescent cell during operation with a minimum brightness loss.
