Abstract
A phosphor screen is provided, characterised in that said screen comprises at least one organozinc compound corresponding to the following general formula I: ##STR1## wherein: A=either carbon or phosphorus Y=--OR.sup.6, --NR.sup.7 R.sup.8, alkyl or aryl, wherein R.sup.6, R.sup.7 and R.sup.8 each independently represent a substituted or unsubstituted alkyl- or aryl group, or wherein R.sup.7 and R.sup.8 together form a ringstructure n=1 when A is carbon n=2 when A is phosphorus.
